摘要
针对宁夏贺家湾水库大坝渗漏问题,采用二维渗流有限元法对大坝坝体2个断面的不同工况进行了渗流计算分析.结果表明,贺家湾水库大坝及其坝基防渗效果较差,贺家湾水库大坝右岸坝肩存在坝基及绕坝渗漏现象,0+303.386断面在正常蓄水位时大坝现状坝基日渗漏量约为248.94 m3,水库渗漏量较大.有限元渗流计算为贺家湾水库渗漏分析提供了依据.
In order to study the seepage of Hejiawan reservoir, two-dimensional seepage finite element method was adopted to two sections seepage computation and analysis of dam in different conditions. The result showed that Hejiawan dam seepage control effect is poor; there are phenomenons of basement seepage and around dam seepage on the right bank of dam. Seepage amount is 248.94 m3 per day on the dam section of 0＋303.386 in normal storage level; Hejiawan reservoir leakage amount is larger. The seepage finite element computation provided basis for seepage analysis of Hejiawan reservoir.
