三峡库区巫山县城新址库岸再造预测

Prediction of the riverside rebuilding in the new site of Wushan dowtown,Three Gorges Reservoir area

在系统分析巫山县城新址地质环境条件基础上，讨论了三峡水库蓄水后新址库岸再造预测的方法，采用典型稳定库岸坡度统计方法确定了不同岸坡结构、岩性组合库岸的最终稳定坡度值，选用坡角地质类比法对库岸再造进行预测，最终库岸再造带宽度在４４ｍ～２０１ｍ。预测结果可作为新城规划与建设的依据。

Based on the analysis of the geoenvironmental conditions of the new site of Wushan downtown,a few predictive methods of riverside rebuilding Three Gorges reservoir are discussed.A final stable gradient of riverside of combination of different slope structures and rock properties was determined through adopting a typical statistics method for stable slopes.By using the geological analog method for slope to predict riverside rebuilding,the width of the rebuilt banks was set to be 44m～201m.The predictive result can be used as the reference for the planning and building of the new downtown.
