Abstract:

The large-scale landslide in Wulong county government is 280?340 m long and 15?35 m thick. Landslide thrust is up to 9 000 kN/m; a row of piles cannot resist such a huge landslide thrust. So multi-row embedded anti-slide piles is used in this landslide treatment. The length of piles is reduced by about 1/3. Project investments are saved. The design and the calculation method of the multi-row embedded anti-slide piles in landslide treatment, which focus on the calculation and analysis of landslide thrust as well as the length of embedded anti-slide pile based on the strength reduction FEM, are described.

Key words: landslide treatment, multi-row embedded anti-slide piles, length design of pile, landslide of Wulong county government, strength reduction FEM
