摘要： 库岸滑坡是三峡库区常见的一种滑坡形式，结合预测库岸再造的卡丘金法、岸坡结构法，针对三峡库区某典型堆积层水库岸坡进行库岸再造预测，基于蠕变理论对滑体及滑带土c、φ值进行折减，计算其长期稳定性。将现状滑坡稳定性与库岸改造后坡形稳定性进行对比分析，综合探讨塌岸引起的形状改变对水库边坡安全性的影响。

Abstract: The landslides along the reservoir banks are very common in the Three Gorges area and current studies on these slides are not comprehensive. The long term stability of a typical colluvial reservoir bank profile is studies using two reservoir bank reconstruction methods: Kachugin Method and Bank Slope Prediction Method. The shear strength parameters of the target profile slope were evaluated by the strength reduction method based on the creep theory. The stability of the current bank and the reconstructed bank are also compared.
