广西中低水头径流电站水库天然岸坡分类方法初探

Natural bank classifying method of the middle and low water head runoff hydropower station reservoirs of Guangxi

中小型径流电站勘测周期短、经费较缺乏，在大多数情况下，水库塌岸调查无法进行较全面的勘探工作。库岸再造的规模、速度与天然岸坡的岩性、结构和形态有极密切的联系。为此以广西右江那吉、邕江西津和桂江京南３个中型径流电站的勘测资料为主要依据，结合其它中小型径流电站的勘测资料，对该类型电站的水库天然岸坡进行分类尝试。

The surveying period of the middle and small type runoff hydropower station is shorter,and fund is lacking, so designers can't survey overall reservoir bank collapsing.The reservoir bank's rebuilding scale and speed are closely related with the natural bank's rock characteristics ,structure and features. Based on surveying materials of the Youjiang Naji ,Yongjiang Xijin ,Guijiang Jingnan and linking the medium small sized runoff hydropower stations of Guangxi,the author tried to classify the natural bank of those hydropower stations.
