摘要
四川省广甘高速公路K43+600~K43+699.5段左侧为大型堆积体斜坡,高速公路以挖方形式从堆积体中部通过。为准确评价挖方边坡及后部堆积体斜坡稳定性,通过工程地质勘察查明了坡体地质结构,推测了潜在失稳破坏模式,基于极限平衡法对潜在滑动面进行了稳定性计算分析,拟定了挡墙支挡和后期监测的处治方案。采用深部位移监测系统对该边坡进一步开展了远程实时监测,根据监测成果综合判断,开挖边坡及后部堆积体斜坡整体处于稳定状态。
The big deposit slope is in the left of K43+600~K43+699.5 on Sichuan Guanggan higway.The engineering geological structure and the failure mechanism of the multi-layer deposit and the stability of the slope were preliminary analyzed based on the field survey.The stability of slope was evaluated in limit equilibrium analysis.The deep displacement remote monitoring was uesd in the slope,the results displayed the slope is in safety.
