Abstract:
The Majiawuchang-Houping landslide lies in Wushan county in the region of the Three Gorge dam area. The main part of new Shuanglong town is on the landslide. The characteristic of the landslide was introduced in detail. A great deal of data about weak structural plane were analyzed, the combinatorial connection of various weak structural planes were studied, and preferred plane theory was used to explain the origin of the landslide. Remained Thrust Method was used to study the stability of the landslide in diverse engineering case. Meanwhile, the stability of the landslide was forecasted after Three Gorge dam area would be inundated. The study indicated that, the landslide was steady at present, and the water of Three Gorge dam area has prodigious influence on the landslide, the landslide would lost its stability after Three Gorge dam area was inundated.
