摘要

拟静力法简单适用

在地震边坡稳定分析中发挥了很大作用

积累了较丰富的经验。传统上滑动体都是按竖向条分的。考虑地震惯性力时

竖向条分在计算地震惯性力和抗滑力矩时存在计算上的不合理

从而使地震惯性力与实际值有误差

抗滑力矩偏小。而考虑地基中的地震荷载时

安全系数的计算结果是不确定的

没有一个客观的最小安全系数计算结果。在分析了误差产生的机理后

对拟静力法的计算进行了改进。算例表明

改进后拟静力法计算结果是合理的。

Abstract

Static method of slope stability analysis is simple and play a distinctive role in slope seismic stability. Sliding mass is traditionally divided by vertical slice. Errors should be induced in calculating horizontal seismic inertial force and anti-sliding moment according to vertical slice. Considering horizontal seismic inertial force in foundation

safety factor is uncertain. The cause of errors and uncertain is analyzed

and an improved method is put forward. Calculating sample shows the improved method is reasonable.
