摘　　要：现场地质勘测结果表明 ,龙王庙滑坡是个由 6个单体滑坡组成的滑坡群。通过室内试验、反演及工程地质类比 ,确定了滑带抗剪强度指标。采用传递系数法及 SARMA法 ,针对三峡工程蓄水后7种不同工况组合 ,对龙王庙滑坡群的稳定性进行了定量评价。在此基础上 ,依据地质环境保护与土地资源有效利用协调一致的原则 ,制定了龙王庙滑坡群的综合整治方案。Practical geological survey reveals that longwangmiao landslides are a massive colony that consists of 6 single slopes. The parameters of anti-shear strength of the sliding zones were determined by laboratory test, inversion and engineering geology analogy. A stability analysis is conducted by the transfer coefficient and SARMA methods for seven working occasions when the Three Gorges Project is completed and the impoundment is implemented. Then, a comprehensive control scheme of Longwangmiao landslides is proposed after considering both geological environmental protection and effective land utilization.
