摘　　要：该文采用数值法计算地下厂房洞室的涌水量,根据抽水蓄能电站的水文地质条件,建立了地下厂房区二维非稳定地下水流数学模型,该模型考虑了厂房周边断层破碎带和厂房上方施工平硐对厂房涌水量的影响。计算结果表明,地下厂房存在断层破碎带时,厂房的涌水量将增加;而平硐起到了很好的排水作用,能有效减小地下厂房的涌水量,平硐距离厂房越近,进入厂房的涌水量越小。In this paper,the numerical method is used to calculate the water yield of cavern in the underground powerhouse. According to the hydrogeological condition of the pumped storage power station,the numerical model of two-dimensional unsteady groundwater flow of the underground powerhouse is built. The model considers the effect to the powerhouse water yield from the fault fracture zone around the underground powerhouse and the adits above the underground powerhouse. The results show when the fault fracture zone in the underground powerhouse the water yield increases. But the adits play a role to drainage,it can reduce the water yield in underground powerhouse effectively. The more shorter distance from adit to powerhouse,the more less water yield enters underground powerhouse.
