粘性土边坡的稳定性分析

陕西南部汉中、安康地区广泛分布有一层粉质粘土， 该层土近似粘土， 含膨胀土矿物， 具有独特的石榴粒状结构， 遇水ｃ、值急骤降低， 极易产生滑坡。 通过对某边坡的稳定分析及挡土墙稳定验算， 采用多种土压力计算理论， 分析边坡滑动时 的ｃ、值变化范围、提出在陕南地区进行挡墙设计时， 参数ｃ、值取值的建议。

Analysis for Slope Stability of Cohesive Soil

There distribut abroad a layer mealy clay in South of Shannan Provinoe Hanzhoge、Ankang area,it's close to clay,contains swelling soil mineral,having inimitable megranate structure,c、 value urgent debase when meeting water,amilible produce slide.How to choose the logical geotechnical parameters to design block soil wall,father slide?In this article,transit analysis of a slop's stability and checking computations to block soil wall stability,adopt many kind of soil tension calculate theory,analyse c、 value diversification and extension when slope sliding,give out the advice of c、 value when design block soil wall in North of Shanxi.
