因埋深大、引水距离长,蒲石河抽水蓄能电站地下厂房排水廊道岩体渗水现象较明显。对此,结合枢纽区地质构造情况、气温变化和地下厂房结构布置等资料,以渗流场和温度场耦合机理为理论支撑,通过研究实测漏水量与气温等影响因子的相关关系,分析了不同区域的渗漏原因。结果表明,周期性变化漏水点的主要渗漏原因为出露的岩体裂隙和气温变化,而非周期性的漏水点漏水主要为内水外渗所致。研究结果可为厂房安全运行提供技术借鉴。
Due to the large buried depth and long diversion distance, seepage phenomenon of rock mass in drainage corridor of underground powerhouse of Pushihe Pumped Storage Power Station is obvious. In this regard, combined with the geological structure of the hub, changes in temperature and the layout of the underground power plant structure and other information to seepage field and temperature field coupling theory as a theoretical support for the study by measuring the correlation between water leakage and air temperature and other influencing factors, analysis of different regions Leakage causes. The results show that the main leakage reason of the periodically changing leakage point is the fissure and temperature change of the exposed rock mass, while the non-periodic leakage point is mainly caused by the leakage of internal water. The research results can provide technical reference for the safe operation of the plant.
