重庆市奉节县挖断村滑坡规模巨大，滑坡体长180～250 m，滑坡体厚15～35 m，剩余下滑力达5337 kN/m，采用了前排全长后排埋入式的新型组合抗滑支挡技术，大大节省了工程投资。介绍了这种新型组合抗滑结构的设计方法，重点介绍了桩的长度计算、各桩承担滑坡推力计算、治理后的监测数据。工程竣工2年的监测数据表明滑坡变形趋于稳定，说明采用全长和埋入式组合抗滑桩治理该滑坡是有效的。

The Large-scale landslide in Waduan village,Fengjie county of Chongqing is 180 to 250 m long and 15 to 35 m thick. The surplus sliding force is 5 337 kN/m. A new combined anti-slide pile structure is used in this landslide treatment. Invest-ment projects have been saved. This article describes the design and calculation method of the combined full-length and embedded anti-slide piles in landslide treatment, which focuses on the calculation and analysis of landslide thrust, as well as the length of em-bedded anti-slide pile. Besides, this paper introduces the field monitoring data. Monitoring data show that the landslide deformation tends to be stable two years after the completion of the project, indicating that the full-length and embedded anti-slides pile in the treatment of the landslide are effective.
