摘要
采用动力有限元分析了软夹层厚度、倾角、埋深等参数对边坡的位移、加速度等动力反应的影响。研究表明:软夹层对边坡动力特性影响显著,在边坡设计和边坡稳定性分析中不能忽视;软夹层越厚滤波和放大效应越明显;软夹层埋深越大,滤波效应越明显;软夹层倾角对滤波效应影响不显著,但对峰值有影响,而逆边坡角的软夹层可以减小边坡表面位移和加速度峰值。研究结论可应用于边坡设计中。
The dynamic finite element method is used to analyzes the influence on dynamic characteristic of the slope by soft soil layer. The parameters which influencing the earthquake response of the slope, including the depth, the thickness, the obliquity of soft soil layer are analyzed. The influence of soft soil layer is obvious, which must be thought over in the analysis of slope stability. The thicker the soft soil layer is, the more obvious the filter and the amplitude effect is. The deeper the soft soil layer is, the more obvious the filter effect is. The filter effect of the obliquity of the soft soil layer to dynamic time history is not obvious.
