南水北调工程十堰方滩乡塌岸预测评价

分析库岸再造的影响因素,结合十堰市方滩乡的库岸地质环境问题,采用典型稳定库岸坡度统计方法确定了不同岩性的最终稳定坡度值,选用坡角地质类比法对研究区的库岸再造问题进行工程地质评价,确定出塌岸带的宽度,从而指导移民规划工作。

Prediction and Evaluation on Reservior Bank Rebuild of the Water Sources Project of South-To-North Water Diversion

The factors impacting the reservoir bank reconstruction are analyzed systematically in the paper.Based on a case study of reservoir bank geological environment of Fangtan Town,Shiyan City,the final stability slope degree value of different lithology is determined by reservoir bank slope degree typical statistical methods,and the engineering geological evaluation of reservoir bank reconstruction is given by slope angle geological analogy method.In this way,the width of collapse bank can be determined,and the result can guide the immigration programming.In order to increasing the area of farmland and programming,the corresponding prevention project is presented.
