Method for determining slope slip surface with gentle inclination weak intercalated layer
The invention provides a method for determining a slope slip surface with a gentle inclination weak intercalated layer The method comprises the following steps of S1, determining a curve formed by a rear edge tension crack surface slip arc, a weak intercalated layer surface and a front edge shear outlet slip arc, namely a slope slip surface; S2, calculating a slip surface stability coefficient byadopting a limit balance method; and S3, determining the position of the surface with the gentle inclination weak intercalated layer, particularly, if the numerical value of the slip surface stabilitycoefficient calculated in the step S2 is less than 1 but close to 1, judging that the determined position of the slope slip surface is accurate, and otherwise, repeating the steps S1 and S2 by movingthe position of the surface with the weak intercalated layer till the slip surface stability coefficient is less than 1 and close to 1. The method for determining the slope slip surface with the gentle inclination weak intercalated layer is simple, has high determining accuracy for a non-arc slope slip surface with the weak intercalated layer as the bottom slip surface, and provides a basis for design of a landslide treatment scheme of the slope with the gentle inclination weak intercalated layer.
本发明提供了一种含缓倾软弱夹层边坡滑移面确定方法，包括以下步骤：S1、确定后缘拉裂面滑移圆弧、软弱夹层面和前缘剪出口滑移圆弧组成的曲线，即边坡滑移面；S2、采用极限平衡方法计算滑移面稳定性系数；S3、确定含缓倾软弱夹层面位置：如步骤S2中计算出的滑移面稳定性系数值小于1但接近于1，则确定的边坡滑移面位置准确；否则通过移动软弱夹层面位置，重复步骤S1和S2，直至滑移面稳定性系数小于1并接近1。本发明提供的含缓倾软弱夹层边坡滑移面确定方法，其方法简单，对于以软弱夹层为底滑面的非圆弧边坡滑移面的确定准确性高，为含缓倾软弱夹层边坡滑坡治理方案的设计提供了依据。
