清原抽水蓄能电站上水库防渗线路工程地质条件比选

Comparison of engineering geological conditions for anti-seepage line of upper reservoir of Qingyuan Pumped Storage Power Station

清原抽水蓄能电站上水库库区三面环山,垭口发育多,全强风化岩体厚度较大,存在单薄分水岭渗漏等问题。防渗线路的选择对防渗效果的影响至关重要,通过对上水库分水岭及环库路工程地质条件进行对比分析,找到合适防渗线路,为防渗布置提供依据。

The upper reservoir area of Qingyuan Pumped Storage Power Station is surrounded by mountains on three sides,and there are many problems such as mountain passes,thick weathered rock mass and leakage in thin watershed.The selection of anti-seepage route is very important to the effect of anti-seepage.The appropriate anti-seepage route is found through the comparative analysis of the engineering geological conditions of the watershed of the upper reservoir and the Huankou Road,and the basis for the anti-seepage arrangement is provided.
