摘　　要：基于丰都楠竹崩滑体的地质勘察资料,对该崩滑体在长江水位从175m降至125m时的稳定性进行了计算分析,得出该工况下,崩滑体将处于可能失稳的危险状态,必须进行防治。然后,在多种防治方案比较的基础上,认为抗滑桩方案在技术经济上最为合理,并提出了一种新的抗滑桩整体设计方法,编制了相应的计算程序,离心模型试验验证了该方法的合理可靠性。最后,通过计算分析,提出了丰都楠竹崩滑体抗滑桩工程的优化设计方案,并建议了确保该崩滑体整体稳定性和局部稳定性的相应辅助工程措施。Based on the geological exploration of Nanzhu landslide, the stability analysis of the landslide is studied when the water level of the Yangtze River falls from 175 m to 125 m. The results show that the landslide will be unstable under this condition. As a result, treatment needs to be carried out. Compared with a pair of treatment schemes, it is found that the anti-slide pile scheme is reasonable. Moreover, a new design method of anti-slide pile and the calculation code are achieved; and it is verified by the centrifugal model test. Finally, the optimal treatment scheme and additional engineering measures are proposed.
