摘要
小浪底厂房为一大型地下工程 ,其特点决定了必须在干燥状态下长期安全稳定运行 .从水文工程地质角度阐述了地下水在岩体裂隙中的运移 ,分析了施工期及运行过程中地下厂房顶拱渗漏产生的原因 ,讨论了排水设计方案和排水效果 ,并预测达到正常高水位后 ,库水不会对地下厂房产生大面积渗漏 ,影响电站的正常运行 .
The underground powerhouse of Xiaolangdi multipurpose dam project is a large size underground structure, which requires dry condition to that its safe operation in a long time. The paper analyzes the flow of underground water in rock joints, and the reason seepage occurs along the crown of the powerhouse during construction. Also the paper forecasts the seepage when the reservoir is operate under normal water level.
