降雨条件下膨胀土边坡稳定性分析

摘要

应用湿度应力场理论，采用ANSYS软件的热—力耦合计算方式，模拟了降雨入渗下边坡土体产生的膨胀效应，并建立了边坡稳定性分析方法，分析了降雨条件下膨胀土边坡的变形破坏规律，为膨胀土边坡处治提供了理论依据。%Based on humidity stress field theory,the paper uses of the coupled thermal-stress function of ANSYS finite element to imitate the rain-fall seepage and expansive force of slope,establishes the slope stability analysis method,analyze the deformation and failure law of expansive soil slope under the condition of rainfall,and have provided a theoretical basis for treatment for the expansive soil slope.
