| 摘 要： | 武隆县政府滑坡规模巨大，滑坡体长280～340 m，滑坡体厚15～35 m，滑坡推力最大达9 000 kN/m，采用一排抗滑桩难以抵挡如此巨大的滑坡推力。设计采用了多排埋入式抗滑桩进行支挡，将桩的长度减小了约1/3，节省了工程投资。介绍了该滑坡采用埋入式抗滑桩的设计计算方法，重点介绍了采用有限元强度折减法对多排桩的推力及桩的长度设计与计算，供同行或类似工程参考。

| 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. |
