摘要

研究平推式滑坡中承压水渗流形式对滑坡稳定性的影响，有利于准确评价斜坡稳定性，对此类滑坡的成灾机制研究具有重要的理论指导意义。基于承压水渗流宽度变化规律，将平推式滑坡中底滑面承压水渗流形式分为辐射流和非辐射流。依据不同的渗流形式，构建了相应的平推式滑坡分析模型，结合地下水向河渠稳定运动相关理论，推导了不同模型中承压水的水头线方程和滑面上扬压力的计算公式，提出了扬压力的3种分布形式，并对平推式滑坡启动判据进行修正，最后结合滑坡实例分析了不同渗流形式对滑坡稳定性的影响规律。

Abstract

It is important to study seepage forms of confined water on translational landslide

which is helpful to accurately evaluate the slope stability and provides a reasonable theoretical guidance for studies on the disaster mechanism on translational landslide. Based on the variation law of seepage width of confined water

the seepage forms of confined water on slide plane of translational landslide are divided into the radiation flow and the non-radiative flow. According to different seepage forms

the translational landslide analysis models are established. Based on the theory of groundwater flow to canals

the water head line equation of confined water and the calculation formula of uplift pressure in different models are deduced. Furthermore

three kinds of uplift pressure distribution forms are put forward

and then the starting criterion of translational landslide is modified. Finally

based on a case of translational landslide

the law of slope stability under different forms of seepage is discussed.
