边坡稳定计算斜条分法机理分析
摘要:利用较严格的通用条分法的分析思路,将边坡条块划分一般化,即采用斜条分法。重新建立了斜条分法的各种平衡方程式,并在此基础上假定斜条块间切向力与法向力满足Mohr-Coulomb准则的函数关系。算例分析表明该方法所求的安全系数与通用条分方法的结果相近,得到的简化计算是可行的。
Abstract:The method for slope is generalized according to the basic analysis thought of rigorous generalized method of slices. It is a subsection method of slope. The author rebuilt each equation under limit equilibrium method. On this basis, an effective simplified algorithm is applied for slope stability analysis. That is the relations function of inter-slice force between tangential grinder and normal direction on the regulation of Mohr-Coulomb. Through study and analysis of a case, the safety factor of subsection method forslope is fairly close to the result of generalized method of slices. The computing result shows the presented method is applicable.
