    边坡的潜在滑动面分析

    ANALYSIS ON POTENTIAL SLIDING SURFACE OF SLOPES

    • 摘要: 边坡稳定分析是土力学的经典课题之一。极限平衡法是边坡稳定分析最常用的方法, 也是规范推荐的方法。通常认为最小安全系数对应的潜在滑动面就是最可能滑动的临界滑动面。本文对这一问题进行分析, 提出了将最大加速度对应的滑动面作为潜在滑动面的思路, 这里称为加速度临界滑动面。对典型算例进行分析, 表明最大加速度与最小安全系数具有较好的相关性。

       

      Abstract: Stability analysis of slopes is one of the classic problems in soil mechanics. Limit equilibrium method is the most commonly used method for slope stability analysis, and it is recommended by many specifications. Generally, the potential sliding surface corresponding to the minimum safety factor is thought to be the critical surface that are most likely to slip. Based on the analysis in this paper, an idea is proposed which considers the sliding surface corresponding to the maximum acceleration as the critical surface, and is called critical surface of acceleration. Examples show that the maximum acceleration is closely related to the minimum safety factor.
