摘要
公路滑坡是安化县重要的地质灾害之一。本文通过对S324牛大公路滑坡勘查,查明了滑坡体基本特征,从地质环境、人类工程活动等方面分析其孕灾、致灾因素。通过稳定性评价分析,表明该滑坡仍处于不稳定状态,结合滑坡特征,提出分级放坡、骨架护坡、挡土墙等防治措施建议。
Highway landslide is one of the important geological disasters in Anhua County.In this paper,the basic characteristics of the landslide mass are found out through the investigation of the landslide of the S324 Niuda highway,and the factors of disaster pregnant and causing are analyzed from the aspects of geological environment and human engineering activities.Through the stability evaluation and analysis,it shows that the landslide is still in an unstable state.Combined with the characteristics of the landslide,the paper puts forward the prevention and control measures such as grading,skeleton slope protection,retaining wall and so on.
