摘要
在大量的野外地质调查工作基础之上,采用赤平投影法分析了沉积岩地区岩石高边坡的潜在破坏模式,并运用极限平衡法计算边坡在此潜在破坏模式下的稳定性,对安全储备较低的采石场边坡提出削坡方案,同时配合有限元法对边坡的稳定性进行了分析和评价,指出岩层层面是影响沉积岩地区高边坡稳定性的最不利结构面,是调查和研究的重点。
Based on field geologic survey, the method of stereographic projection was adopted to analyze the potential failure mode of high rock slope in the sedimentary rock areas. According to the potential failure mode, the methods of limit equilibrium were applied to analyze the stability of the slope. A scheme of cutting the quarry slope with lower safety was putted forward. Meanwhile, FEM was also used to analyze and estimate the stability of the slope. It is considered that bedding plane is the worst structural plane affecting the stability of high rock slope in the sedimentary rock areas. As a result, it is a key point to survey and study.
