对抽水蓄能电站关键工程地质因素的一些认识

Some Understanding of Key Engineering Geological Factors of Pumped Storage Power Stations

从20世纪80年代起,中国开始陆续建设了一批大中型抽水蓄能电站,积累了针对不同地形地质条件的丰富工程建设经验。近期在双碳目标引领下,抽水蓄能电站建设迎来快速发展期。通过对抽水蓄能电站建设重点关注的地形条件、渗漏特征、地下洞室围岩稳定、天然建筑材料利用等主要工程地质因素和问题进行归纳总结,探讨了各要素分类特征,并对典型案例进行了分析,可为后续电站建设的地质工作思路提供参考。

Since the 1980s,China has begun to build a number of large and medium-sized pumped storage power stations,and has accumulated rich engineering construction experience for different terrain and geological conditions.Recently,under the guidance of the dual carbon goals,the construction of pumped storage power stations has ushered in a period of rapid development.By summarizing the main engineering geological factors which are focused on in the construction of pumped storage power stations,such as terrain conditions,leakage characteristics,underground cavern surrounding rock stability,and the use of natural building materials,the classification characteristics of each factor are discussed,and typical cases are analyzed,which can provide a reference for the geological work of subsequent power station construction.
