| 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 sub-section 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 sub-section method forslope is fairly close to the result of generalized method of slices.The computing result shows the presented method is applicable. |
