摘要:
基于三维滑坡模型和简布（Ｊａｎｂｕ．Ｎ）的简化假设，将粘性土坡的稳定性问题等价于１个双参变量函数的待定边界的泛函的变分问题，利用变分法，推导了滑裂面所应满足的偏微分方程（欧拉方程）和横截性条件。本方法可以确定三维滑裂面形状和安全系数，同时可研究滑坡的宽度效应。
Abstract:
Based on the simplified assumptions of the three -dimensional slippery model and Janbu.n, the stability problem of the viscous soil slope is equivalent to the problem of the generalization of the generalization of the border of the border of the dual -cinior function, and uses the change method to derive the partial micro -division equation (Euler equation) and cross -deserved conditions that should be met by the slippery surface. This method can determine the shape and safety factor of the three -dimensional sliding surface, while studying the width effect of the landslide.
