总结国内外土与结构接触面力学特性研究的现状,系统介绍接触面力学特性研究领域在试验模拟、本构模型以及计算方法方面的进展,分析不同试验仪器的特点,讨论现有接触面模型及计算方法的应用条件和存在的问题,指出:土与结构接触面复杂应力状态及高应力状态下特性研究、剪胀(剪缩)测试及颗粒破碎机理研究,特殊土与结构接触面的力学特性研究以及接触面动力特性研究等是今后研究的主要方向.

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.
