摘　　要：天生桥一级水电站坝高库大 ,地质条件复杂 ,坝区岩体是由岩性各异岩层组成的单斜地层结构 ,并发育有数条断层 ,坝区地下水渗流场的变化情况是大坝安全运行必须考虑的重要因素之一。本文将双重裂隙系统渗流模型应用于天生桥一级水电站的三维渗流计算中 ,对不同工况下的坝基岩体和坝体渗流场的变化特征及坝基渗漏量进行了初步分析 ,其结果可为水库运行管理提供参考。Tianshengqiao 1 st grade hydro\|power station is a large reservoir with the volume of 10\^26Gm\+3 and with the installed capacity of 1200MW.The dam is 178m high,which is a rock\|filled dam with concrete face.The rock masses in the dam site are of different character rocks with monoclinic stratum constitution and with many faults,such as major fault F\-1 and F\-8,etc.,which make the geological conditions very complex.The seepage flow in the area of the dam site is one of the significant factors concerning the safety of hydro\|power station. The seepage flow model in double fractured systems is used in this paper to analyze the seepage flow in fractured rock masses in the area of Tianshengqiao hydro\|power station so as to make clear how the seepage flow will go and how much discharge will appear under different working conditions.A series of useful conclusions that can help the station to operate safely have been summarized.
