摘要
从试验研究、本构模型和数值模拟3个方面对国内外高土石坝接触问题的主要研究成果及不足之处进行简要总结和回顾,简要分析了高土石坝接触问题研究中应重点关注的问题。在此基础上,建议今后对高土石坝接触问题研究应注重高应力循环荷载作用下的试验研究、整体离心模型试验研究、渗透破坏试验研究及基于直接约束的接触力学分析方法。
Achievements and shortages in the contact problems of high earth-rock dams at home and abroad are briefly summarized and reviewed in terms of experimental study, constitutive models and numerical simulation. The problems that should be of special concern in the contact problems of high earth-rock dam are also briefly analyzed. On this basis, it is suggested that the contact problems of high earth-rock dams under high stress and cyclic loadings should be studied intensively through experimental study, centrifugal model tests and the contact mechanics analysis method, which is based on the direct constraint model.
