摘要
针对传统土压力理论不能考虑挡墙位移对土压力计算影响的事实,建立了一个能考虑挡墙位移非线性影响的土压力计算模型,并讨论了模型中参数的影响和计算方法。离心模型试验表明,应用提出的模型的计算成果与试验实测值符合,该模型能较准确地考虑挡墙位移对土压力的非线性影响,从而为基坑开挖中的土压力计算提供了一种新的计算方法。
Facing up the fact that traditional earth pressure theory can not consider the effects of the displacement of retaining wall on earth pressure calculation,a new earth pressure calculating model considering the nonlinear effects of the displacement of retaining wall was set up,and influences and calculating ways of the parameters were studied.Centrifuge model tests showed that the calculating results of the model are coincident with the tests data.So the calculating model is credible,and it provides a new calculating way for earth pressure calculation.
