基于GEO-Slope的某高速公路边坡稳定性分析

Stability Analysis of a Highway Slope Based on GEO-Slope

某高速公路挖方边坡位于山区陡斜坡上,路基开挖后形成高约59m的高边坡。为了评价施工后边坡的稳定性及为设计提供完整地质资料和设计参数,本文基于GEO-Slope软件建立了原始坡面和开挖边坡的计算模型,采用原始坡面计算模型对岩土体物理力学计算参数进行校验,通过该软件对处于不同工况下的开挖边坡进行定量分析评价,为边坡的防护及支护设计提供了详实的勘察资料和重要的指导作用。

highway excavation slope is located on a steep slope in a mountainous area. After subgrade excavation, a high slope with a height of about 59 m is formed. In order to evaluate the stability of the excavated slope and provide complete geological data and design parameters for the design, this paper establishes a calculation model of the original slope and excavated slope based on the GEO-Slope software. The mechanical calculation parameters were verified, and the software was used to quantitatively analyze and evaluate the excavated slopes under different working conditions, Provides detailed survey data and important guidance for slope protection and support design.
