放坡填筑在三峡库区人工填土岸坡治理中的运用

Application of Building Slope with Filling Soil in Governance of Artificial Fill Slope in the Three Gorges Reservoir Area

对三峡库区填土岸坡变形特征及影响因素进行分析,并对其稳定性进行了计算评价,分析认为人工填土岸坡稳定性差,易发生下沉、开裂、坍塌和泥石流灾害。通过对填土岸坡采用放坡填筑的治理措施,达到了治理库岸变形的目的,防治效果好。

The paper analyzes deformation characteristics and influencing factors, evaluates its stability of fill slope in Three Gorges reservoir. The results show that artificial fill slope stability is poor, and geological disasters including sinking, cracking ,collapse and debris flow take place most easily on artificial fill slope. Through the use of method for building slope with filling soil on fill slope, it obtains the aim of controlling the deformation of reservoir banks. The control effect is good.
