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。
The Tianshengqiao-1 hydropower station has a large dam height and a large reservoir with complex geological conditions. The dam rock mass is a monocline structure composed of various lithologic rock layers and has several faults. The change of groundwater seepage field in the dam area is the safe operation of the dam One of the important factors that must be considered. In this paper, the double fracture system seepage model is applied to the three-dimensional seepage calculation of the Tianshengqiao-1 hydropower station. The variation characteristics of the seepage field and the seepage of the dam foundation under different working conditions are analyzed preliminarily. The results can be Reservoir operation and management for reference.
