Review of researches on macro・-mechanical properties and meso・-mechanical methods of unsaturated concrete LIU Hong-biao (TianjinResearchInstitutefor Water TransportEngineering,KeyLaboratory ofHarbor&MarineStructureSafety, Ministry ofTransport,Tianjin 300456,China) Abstract:Macro—mechanical parameters of unsaturated concrete are important for concrete structures design in harbor engineering.The study on experiment,meso—mechanical analysis methods and meso-mechanical ifnite ele— ment methods of macro—mechanical properties of unsaturated concrete were reviewed in this paper.The experimen— tal research achievements,the characteristics and applicability of current meso-mechanical analysis methods and meso-mechanical ifnite element methods on macro—mechanical properties of unsaturated concrete were summarized. The influence factors of macro.mechanical properties of unsaturated concrete were described.Based on above,the development trends of macro—mechanical properties of unsaturated concrete in mechanical experiment,meso—me— chanical analysis theory and meso—mechanical finite element methods,as well as the problems to be solved were summarized and prospected.
