摘要
文章利用达州市渠县李馥乡南阳碥滑坡治理工程勘察、设计资料，结合现场实际情况，补充了勘察资料对滑坡．认识上的一些不足。针对2号滑坡中前部和中后部不同的变形破坏特征，对其成因机制进行了详细分析和认识，指出南阳碥滑坡不稳定2号滑坡体中后部房屋开裂变形的主要原因是坡体地下水位埋深过浅（1～3m），整个坡体基本处于饱水状态，由此导致地基承载力不足，房屋出现不均匀沉降。而滑坡体中前部房屋开裂和坡体的变形破坏则主要是由于汛期渠江水位的大幅度升降导致库岸边坡失稳以及降雨诱发坡体局部滑动。文章对滑坡体进行了稳定性评价及滑坡推力计算，按照4种工况对各个不同的剖面提出了相应的抗滑支档＋截排水工程的治理措施。
The paper supplements the deficiency of acknowledge to Nanyangbian landslide in Dazhou, Sichuan Province, using the data of surveying and designing for treating the landslide. According to the different deformation features between the middle-ahead and middle-back of landslide, it was found that the cause of the craze and deformation of the house of middle-back of the number 2 landslide is shallow（1 - 3m） underground-water. All of the slope is lull of craoks becauke of the lack of carrying capacity of the groundwork, the houses asymmetrily subsides. In the other hand, the main cause of the craze and deformation of the house of middle-ahead of the landslide is the bank astaticism for the Qu River＇ s water-level r/sing and dropping at the time of flood season and the local slippage for the rain. At last, the paper asseses the landslide stability and computes the landslide thrust force of the landslide. According to the different sections, it is suggusted that the landslide treatment measures of anti-slide, retaining and intercepting and drainage structure, the conclusion and proper advice.
