大藤峡水利枢纽右岸滑坡体综合治理方案研究

Study on comprehensive treatment plan of landslide mass on right bank of Datengxia hydro junction

文中论述了大藤峡水利枢纽工程右岸滑坡体的成因及复杂的地质条件,针对滑坡体上部全强风化岩体、中部塌滑堆积物、底部弱风化及下部基岩内存在多层顺坡向软弱夹层的地质状况,通过稳定分析计算,进行多方案技术经济比选,提出较为合理的设计方案,为相似地质条件的边坡治理设计提供参考。

The paper discusses the cause of the landslide mass on right bank of the Datengxia hydro junction and the complex geological conditions.According to the geological situations including the complete highly weathered rock mass at the upper part of the landslide mass,the collapse deposit in the middle part,the moderately weathered rock at the bottom part,and the base rock with along slope multilayer weak intercalated layer at the lower part,through the stability analysis calculation,the paper carries out technical and economic comparison among multi schemes and puts out the reasonable design scheme,which could provide reference for side slope treatment design with similar geological conditions.
