摘要
土与结构界面力学特性的研究是解决土与结构物相互作用的前提。介绍特殊直剪试验及特殊单剪试验在界面力学特性方面的研究发展状况及研究成果和不同界面单元的优缺点及工程应用情况,不同本构模型及参数选取方法在界面数值计算中的应用,分析和讨论现有界面试验及数值模拟中存在的问题,提出影响界面力学特性因素的定量研究将是未来的研究方向。
Study on mechanical properties of interface between soil and structure is a prerequisite for solving of soil-structure interaction. This article mainly introduces the study development and research of interface on mechanical properties by the direct shear test and simple shear test, it also introduces the advantages and disadvantages of different interface element and its application in engineering, what＇s more, it also introduces the different constitutive model and the way of parameter selection in applications of numerical calculation of interface, analyses and discusses the existing problems in the experiment and numerical simulation of interface, and proposes quantitative study of influence factors on mechanical properties of interface will be the future research directions.
