Abstract:
Some advances in test simulation, constitutive model, and calculation method in mechanical behavior study of soil-structure interfaces at home and abroad were systematically summarized. The characteristics of different test apparatus were analyzed, and the application conditions of the current soil-structure models and the calculation methods as well as some related problems were discussed. It is pointed out that the studies on mechanical behaviors of soil-structure interfaces under complex stresses and high stresses, shear dilatancy （shear shrinkage） test methods and grain crushing mechanism, mechanical characteristics of special soil-structure interfaces, and dynamic behaviors of interfaces are the main directions of further research.[著者文摘]
