  6. In this paper the friction piles are used in zipingpu multi - purpose dam construction project, the spillway in the side slope is covered with overburden, the horizontal area is from sp. 0 + 200m to sp. 0 + 280m, the elevation is about from el. 810m to el. 950m, there is hard and integral rock under the overburden, which provides enough anchor ability, and it ' s requirement to set the friction pile at the appropriate place ; in order to improve the slope stability that suitable excavation or weeding off the disadvantage load on the landslide are good measures, for the scarp it ' s better to reduce the slope

    摘要紫坪鋪水利樞紐工程溢洪道樁號0 + 200 ~ 0 + 280 、高程810 ~ 950m范圍的內側邊坡為覆蓋層邊坡，坡體下部有較為完整堅硬的巖石，具備提供足夠錨固力的條件，在適當的位置可以考慮設置抗滑樁，再通過適量的開挖提高邊坡穩定性，或將滑坡體上部不利於穩定的荷載挖除，對于陡坡的坡面可以將坡削緩，則效果會更好。
