达州环城路加油站顺层岩质边坡稳定性分析

对达州环城路加油站顺层岩质边坡稳定性进行了现状和预测性分析，确定该边坡层面和裂隙面多为不稳定结构面；开挖后，在外部营力作用下，边坡可能沿岩层面发生整体或局部的滑动破坏；以坡脚位置层面为潜在滑动面进行分析，暴雨工况下边坡不稳定；提出了防治方案建议。研究结论能够对类似的工程有一定的借鉴作用。

Stability Analysis of a Syncline Bedded Rock Slope near a Gas Station

A syncline bedded rock slope is near a gas station on the northwest side of Fengwu Community, which is on the InnerCity Loop Road, Dazhou City. This paper presents the stability evaluation of the rock slope. The results indicated that, the bedding plane and the fissured surface are unstable structural surfaces. The stability of the excavated slope will be a concern due to the potential slip within the structured weak suface, especially, under the heavy rains. The paper also provides slope stability mitigation measures.
