基于SLOPE/W的边坡稳定性分析

Slope Stability Analysis Based on SLOPE/W

摘要: 本文以某边坡为设计对象，分析了其稳定性并设计了相应的支护方案。基于软件SLOPE/W分析了无支护结构的某边坡的稳定。在建模过程中，采用了Morgenstern-Price法、Spencer法、Bishop法和Janbu法进行边坡稳定性分析，土层模拟中材料模型选择Mohr-Coulomb模型。分析时，分别考虑了天然工况、地震工况和暴雨工况。结果表明：在三种工况下边坡都处于不稳定状态。根据边坡实际情况，对边坡进行了支护设计，以保证其稳定性，支护结构类型选择了重力式挡土墙。边坡在进行支护设计后，其稳定性得到了显著的提高，本文针对边坡设计的重力式挡土墙，不仅能够保证边坡安全，还能够为项目中其余边坡的支护设计提供一定参考。

Abstract: This article takes a certain slope as the design object, analyzes its stability, and designs corresponding support schemes. The stability of a certain slope without support structure was analyzed based on the software SLOPE/W. In the modeling process, the Morgenstern Price method, Spencer method, Bishop method, and Janbu method were used for slope stability analysis, and the Mohr Coulomb model was selected as the material model for soil simulation. In the analysis, natural conditions, earthquake conditions and rainstorm conditions are considered respectively. The results indicate that the slope is in an unstable state under all three working conditions. Based on the actual situation of the slope, a support design was carried out to ensure its stability, and a gravity retaining wall was selected as the support structure type. After the support design of the slope, its stability has been significantly improved. This article focuses on the gravity retaining wall designed for the slope, which not only ensures the safety of the slope, but also provides some reference for the support design of other slopes in the project.
