基于强度折减法的膨胀土渠道边坡稳定分析

The analysis of expansive soil slopes stability based on strength reduction

以南水北调中线工程总干渠陶岔渠首至沙河南段工程鲁山段边坡工程实践为基础,建立膨胀土边坡稳定分析模型,对膨胀土渠道进行有限元分析,提出浅层滑坡是膨胀土边坡失稳的主要形式,应根据膨胀土的特性来进行膨胀土边坡稳定计算分析。

According to the main canal of the middle route of water project transfer from South-to-North Taocha headworks to the south section of Shahe south segment of Lushan segment slope engineering,an expansive soil slope stability analysis model is established,which analyzed expansive soil canal with finite element;it put forewords the main form of shallow landslides is expansive soil slope instability, it should be analyzed expansive soil slope stability based on the characteristics of expansive soil.
