摘要
重庆—贵州高速公路向家坡滑坡为一路堑边坡,由于开挖、降雨及地下水等重要因素的影响,经治理后边坡仍然在缓慢变形之中,目前仍处于欠稳定状态,滑坡随时有继续滑动破坏的可能,一旦失稳,直接危及公路及立交桥正常营运,可能造成不可估量的损失。因此,对其进行稳定性分析及防治对策研究显得尤为重要。通过对该滑坡的工程地质条件、形态分布特征分析其形成机制及稳定状况,并提出建议防治措施。此成果为该滑坡的有效防治提供了重要依据,同时为公路边坡的后续研究提供有价值的参考。
Xiangjiapo landslide alongside Chongqing—Guizhou Expressway is characterized with cutting slope.Because of the effect of cutting,raining and groundwater,the slope is distorted continuously and is lacked of stability after being controlled.At present,it has the possibility of losing stability and it will endanger roads and crossroads around the landslide.By analyzing the landslide′s engineering geological condition,configuration characters,developing mechanism and stability,the synthetic preventive treatment measures to the landslide are proposed.These measures provide important reference to the control of such kinds of landslides and further study of Xiangjiapo landslide.
