水库库岸再造是水利水电工程中经常遇到的工程地质问题之一 .依据库岸地质结构和岩性组合 ,划分出工程地质条件相近的库岸段 ,与工程地质条件相类似的稳态坡形进行类比 ,确定出再造后的稳态坡形的坡角大小 ,从而进行库岸再造预测 .利用稳态坡形类比法对三峡库区迁建新址的基岩库岸进行了再造预测 ,定量预测出三峡水利枢纽工程建成蓄水后 ,巫山县城新址基岩库岸最终再造带宽度在 40～ 16 6m之间 ,预测结果可以用来指导新城的规划与建设 .
Reengineering of reservoir banks is one of the engineering geological problems often encountered in water conservancy and hydropower projects.According to the reservoir bank geological structure and lithology combination, the reservoir bank sections with similar engineering geological conditions are divided, and the steady slope with similar engineering geological conditions Shape analogy to determine the size of slope angle after reengineering steady state slope, so as to forecast bank-bank reconstruction.Using steady slope analogy to rebuild the bedrock bank of the new relocation site in the Three Gorges Reservoir area, After the completion of the Three Gorges Project, it is estimated that the width of the final reconstruction belt at the rocky bank of the new site of Wushan County is between 40 and 16 6 m. The forecast result can be used to guide the planning and construction of the new city.
