某楔形体滑坡的稳定性分析和治理实践

Stability Analysis and Treatment Practice of a Wedge Landslip

通过对山西省某岩质边坡进行工程地质条件分析、节理裂隙面测量数据统计和赤平投影分析,判定该岩质边坡能够发生楔形体滑动,根据边坡的破坏形式和边坡稳定性的影响因素,利用刚体极限平衡法对楔形体进行稳定性计算和评价,并在此基础上提出该岩质边坡的治理方案,指出该边坡的稳定性分析过程和治理方案能够为类似边坡的治理提供思路和借鉴。

Through the analysis of engineering geological conditions, the surveying data statistics of joint fissure surface and the analysis of stereographic projection, a rock slope in Shanxi Province is determined to be wedge slide. Based on the dam- age form of slope and the factors influencing the stability, the stability of the wedge is analyzed and evaluated using rigid body limit equilibrium method, and the treatment scheme is proposed. It can provide new ideas and references for other simi- lar slope treatment.
