摘要
洮河三甲水电站运行至今已有24a,需进行泵站更新改造,故要对洮河三甲水电站工程区基本地质条件及存在的工程地质问题进行评价分析,主要是从地形地貌、地层岩性、物理地质现象、地质构造与不良地质现象、水文地质等方面进行全面论述,对库区渗漏、水库浸没与库岸稳定等地质问题进行评价,进一步对坝基及坝肩等地质条件进行分析和评价,为下一步水电站更新改造提供技术指导.
Abstract
Taohe Sanjia Hydropower Station has been in operation for 24 years and requires pump station renovation and renovation.Therefore,it is necessary to evaluate and analyze the basic geological conditions and existing engineering geological problems of Taohe Sanjia Hydropower Station project area.This paper mainly comprehensively discusses the terrain,lithology,physical geological phenomena,geological structures and adverse geological phenomena,hydrogeology,and other aspects.It evaluates geological problems such as reservoir leakage,reservoir immersion,and reservoir bank stability in the reservoir area.Furthermore,it analyzes and evaluates the geological conditions of the dam foundation and shoulder,providing technical guidance for the next step of hydropower station renovation.
