摘要
提出了一种通过应力路径试验研究土压力-位移关系的方法。通过室内应力路径试验得到了土压力-应变关系,结合由理论分析得到的位移-应变关系,最终得到土压力-位移关系。与某实例的有限元模拟结果对比,证明该方法是有效的。
A research technique about the relation between soil pressure and displacement is given. In the method, two relation are gained. One relation is between soil pressure and strain from tests of stress paths; the other given by theoretical analyses is between displacement and strain, then the relation between soil pressure and displacement is obtained in response to the two relations mentioned above. According to the finite element analysis of an example, the research technique is proved to be easy and practical.
