| 摘 要： | 文章介绍了一个位移土压力模型,将经典土压力理论引入该模型中,并与已有的2组模型试验比较,证明了该方法的可行性与合理性;分析了内摩擦角与极限位移量的变化对模型的影响;将本模型与其他已有位移土与压力模型进行比较,结果表明:各个模型均是基于不同的角度对位移与土压力关系进行拟合的,因此模拟出来的结果与实测值均存在一定的差异;但本模型模拟实际土压力状态的准确性较好.

| Abstract: | An earth pressure model considering displacement is introduced,and classical earth pressure theories are applied to this model.The comparison between the computation results and two model test results are made.The model is proved to be feasible and reasonable.The influences of the changes of internal friction angle and limit displacement on the model are analyzed.By comparing the model with other models,a conclusion is drawn that the computation results of the models do not agree well with the test results ... |
