通过对等圆心角斜条分法(D条分法)及传统条分法求解安全系数过程的分析,定性地分析了D条分法与传统条分法的不同之处,再结合澳大利亚ACADS考核算例计算结果,对D条分法与传统条分法的差异加以定量分析,同时也对定性分析结论的正确性加以验证.结果表明,D条分法与传统条分法已经有很大程度的不同,当平均应力水平接近于0或1时,所得出的安全系数与传统条分法得出的安全系数的差异将更大,应直接采用平均应力水平来评价土坡的稳定性.

Through analysis of the solution processes of safety factors using the gradient slice method with equal central angles (referred to as the D slice method) and the traditional slice methods, the difference between them was qualitatively analyzed. Furthermore, based on the calculated results of three examples from ACADS, Australia, the above difference was quantitatively analyzed, and the accuracy of the result of the qualitative analysis was validated. The results show that the D slice method is quite different from the traditional slice methods, especially when the average stress level is close to 0 or 1. In that case the difference between the safety factors of the present and traditional methods will be larger. The average stress level should be used to directly evaluate the stability of soil slopes.
