Xinjiang high speed railway, the frost heaving of coarse-grained filling material was studied through frost heaving tests in both closed and open systems for subgrade filling materials from four gravel-soil-taken fields with different fine particle contents and water contents. Results show that frost heaving may occur in coarse-grained filling material containing fine particles at the time of freezing, and the frost heaving ratio depends on the content of fine particles, water content before freezing and water supply during freezing. In closed system, the frost heaving ratio increases with water content and fine particle content. When the fine particle content is 3. 76%〜21. 46%, the frost heaving ratio of saturated filling can reach 1- 1%
〜2. 2%.
In
winter, the frost heaving produced during freezing will exceed the vertical deviation management value of the ballastless track for high speed railway, which will result in frost damage to subgrade. The frost heaving ratio of filling in open system is far greater than that in closed system,and it can reach 3. 45%
〜
4. 7% when the compacting factor is 0. 93. Obviously, the first choice of measures for the subgrade frost damage treatment of high speed railway is controlling fine particle content and well designing waterproof and drainage facilities.

horizontal stiffening cable on the top of towers, adding stable cable on the middle tower and adding 1 to 3 pairs of cross cables > were studied by finite element simulation and model test. Results show that the three reinforcement measures can significantly increase the vertical stiffness of the bridge. As long as the section area of the stiffening cable is increased,the ratio of deflection to span under static and live loads of Dongting Lake Bridge can be decreased from 1/436 without reinforcement to less than 1/500. When the ratio of deflection to span decreases to the same value between 1/500 and 1/600,
considering the
longitudinal displacement at the top of the middle tower and the bending-moment at the bottom of the middle tower, the effect of adding stable cables on middle tower is better than that of adding horizontal stiffening cables on the top of towers, and much better than that of adding cross cables. The economic benefit of adding stable cable on middle tower is far superior to increasing the stiffness of the main truss of bridge or towers directly. When the ratio of deflection to span is decreased from 1/436 to 1/500〜1/600 by adding stable cables on middle tower, the additional material cost for adding stable cables on middle tower needs only RMB 1. 65〜6. 46 million,the additional cost for increasing the stiffness of all the members of main truss needs RMB 58. 83〜169. 43 million,the additional cost for increasing the stiffness of the three towers needs RMB 70. 08〜229. 94 million,and the additional cost for increasing the stiffness of middle tower alone needs RMB 29. 75〜116. 06 million. The research results have been applied to the design and construction of Dongting Lake Bridge of Menghua Railway.

Abstract: Based on pantograph-catenary contact characteristics, a simulation test method for pantograph-
catenary relation of high speed railway with the train speed of 500 km • h_1 was proposed. The contact wire was installed on the disc and the running speed of the locomotive was simulated by the rotating speed of the disc. The catenary stagger was simulated by the horizontal motion of the disc? and the catenary vibration was simulated by the vertical motion of the disc. The pantograph was installed on the vibration platform, which vibrated according to the actual track irregularity, and the influence of EMU vibration on the pantograph was simulated. A test rig for high-speed pantograph-catenary relation was designed. It was verified that the waveform had good following performance and repeatability in the process of simulating catenary vibration. The measured results of East Dezhou—West Jinan section of Beijing-Shanghai high speed railway show that, the wear ratios of contact lines are about 0. 005 and 0. 006 mm2/ten thousand bows respectively. Based on the measured parameters of catenary and pantograph, the comparison test scheme is designed, the wear ratios of contact line samples obtained from 3 groups of tests are 0. 004,
0. 004 and 0. 005 mm2/ten thousand bows respectively. It shows that the simulation test can simulate the
wear of the contact line close to the actual 5 and the reliabilities of the test method and the test rig for highspeed pantograph-catenary relation are verified.

(Standards &• Metrology Research Institute, China Academy of Railway Sciences, Beijing 100015, China)
Abstract : The catenary of elastic chain type widely used at present for high speed railway in China was
taken as the research object. The dynamic uplift of integral droppers obtained from field tests was used as the initial load of finite element simulation. The installation and construction process of the messenger wire, the contact line and integral droppers was simulated with the finite element model of catenary established by ANSYS software. Based on simulation results, the form-finding analysis and transient dynamics analysis for the catenary were analysed, and the changes of tension, compression and dynamic force of integral dropper under the action of pantograph were studied. Results show that the dynamic force of the integral dropper fluctuates greatly, which is about 6 times of its static force when the pantograph passes through. In the same span, the largest force fluctuations occur on number 1 and 5 integral droppers and with the maximum amplitude of compression. The compression frequency of number 3 integral dropper is the maximum.

Real-Time Control Method for Communication Network of
High-Speed EMU Based on T-S Fuzzy Model
ZHANG Tong
(School of EMU Application and Maintenance Engineering, Dalian Jiaotong University, Dalian Liaoning 116028, China)
Abstract: A MVB network control system was established, including the forward channel delay between
the controller node and the actuator node as well as the feedback channel delay between the controller node and the sensor node. The acquired delay data showed the characteristics of random distribution. Autoregressive model and least mean square algorithm were used to predict forward channel delay. Considering the characteristics of the key control system of train, the nonlinear system was described as a number of linear subsystems near different steady-state operating points. A nonlinear network control system model was established based on T-S fuzzy model, and the generalized predictive control method based on the rolling optimization of state space was designed for each subsystem. The control effects with different control methods, sampling periods and load rates were simulated. Results show that the GPC delay control method based on T-S fuzzy model can accurately track reference signals with different frequencies. Compared with the fuzzy adaptive PID method, this method can better suppress the effect of time delay on control performance. It has ideal robust performance and stability performance, and can fully satisfy the requirements for the real-time control of high-speed EMU running process.

2. National Research Center of Railway Intelligence Transportation System Engineering Technology, Beijing 100081, China)
Abstract: In view of the complexity of the CBTC interlocking system,
a formal method based on the
integration of Communication Sequential Process (CSP) and B method was proposed. Namely, a one-to-one mapping relationship was established between the communication events of CSP and the abstract machine operations of B method,to achieve the goal that communication events could affect the states of abstract machine by controlling abstract machine operations, and to realize the synchronization between CSP and the B method accordingly. Taking an actual station as example, B method was adopted to build abstract machines for the logic state calculation of CBTC interlocking system with complex state space. CSP was adopted to set up the processes for the concurrent interaction behaviors between CBTC interlocking system and external systems. Through the mapping relationship, the abstract machines of CBTC interlocking system and the processes of external interaction behaviors were synchronized, thus a formal model of CBTC interlocking system was established based on CSP and B method. The ProB tool was used to verify the safety, deadlock-free of the model of CBTC interlocking system. The errors in the model were found and modified, such as inconsistence, incompletion, ambiguity and so on. The safety and deadlock-free of CBTC interlocking system were verified, and the final implementation of the system was guaranteed.

Fast Generation Algorithm for Emergency Disposal Information in Earthquake Early Warning System for High Speed Railway
YANG Lin
(Signal &■ Communication Research Institute, China Academy of Railway Sciences, Beijing 100081, China)
Abstract: Based on the structure and function of the earthquake early warning and monitoring system for
high speed railway, a fast generation algorithm was proposed for the emergency disposal information in earthquake early warning system for high speed railway. The curve fitting method was used to establish the curve equation of high speed railway line in plane coordinate system. Based on the energy attenuation equation of ground motion, the circular curve equation of the earthquake affected range in plane coordinate system was established. Two equations were connected and solved, and the coordinate values of 2 intersection points of 2 curves were obtained. The coordinate values were transformed into longitude and latitude and then converted to kilometer scale, and the influence range of earthquake on high speed railway line was obtained. According to the principles of early warning and earthquake emergency disposal for high speed railway, the emergency disposal information of earthquake early warning for high speed railway was generated. The algorithm was applied to the tests and the field seismic experiments for the center system of railway administration in the earthquake early warning and monitoring of high speed railway. The maximum time for generating emergency disposal information was 40 ms, with an average of 18 and 27 ms respectively? which was far less than the required emergency disposal time of 100 ms for the center system of railway administration in w Interim Technical Conditions for High Speed Railway Earthquake Early Warning and Monitoring System”,which verified the rationality and validity of the algorithm.
