在山区修建高速公路不可避免要对山体进行开挖,形成路堑边坡,而路堑边坡的稳定性将直接影响着公路的正常运营。对于在滑坡体上进行开挖的路堑边坡,路堑开挖后滑坡体稳定与否将严重影响着过往车辆的安全,因此研究滑坡体上路堑边坡的稳定性具有重要意义。本文以厦门至成都高速公路(贵州境)清镇至织金段K15+148处滑坡体路堑边坡稳定性为工程背景,采用规范推进方法,对该边坡稳定性进行分析,提出相应的处理措施,为类似工程提供参考。
The construction of expressway in mountainous area inevitably excavated the mountain and formed a cutting slope, and the stability of cutting slope will directly affect the normal operation of the highway. For the cutting slope excavation on the landslide body, the stability of the landslide body after the cutting excavation will seriously affect the safety of passing vehicles. Therefore, it is important to study the stability of the cutting slope on landslide body. In this paper, the stability of the slope at the slope of K15 +148 from Qingzhen-Zhijin Section of Xiamen-Chengdu Expressway (Guizhou) to the slope is taken as the engineering background. By adopting the standard propulsion method, the stability of the slope is analyzed and the corresponding treatment Measures for the similar projects provide a reference.
