长江三峡马家沟滑坡稳定性评价及治理措施

Evaluation of stability and contraling scheme demonstration of the Majiagou landslide located in the three gorges reservoir of Changjiang river

在对长江三峡库区秭归县马家沟滑坡的详细勘测基础上,阐述了其特征和成因机制,并采用推力传递法对主滑剖面按不同工况进行了稳定性计算,评价了其稳定性,在此基础上提出了以抗滑桩、地表排水相结合的治理方案。

Based on the detailed investigation of the Majiagou landslide in the Three Gorges Reservoir of Changiiang River, this paper expatiates on the characters and the genetic mechanism of these geologic bodies, and calculates the stabilities of the landslide to the main dangerous landslides under different loads by use of the imbalance thrust force method （ITFM）, evaluating the stabilities of them. Aarrys out controlling scheme, which combines surface drainage and anti-slid piles.
