摘　　要：在无量水堰的前提条件下,为监测三道湾水电站坝基渗流量,在坝后覆盖层中布设测压管监测系统,在满足一定误差要求的条件下,依据水力坡降法推导出三道湾水电站坝后河床渗流量计算公式,计算得出2012年汛期坝后河床平均渗流量为58.06L/s,并基于坝后渗流的影响因素,提出增设坝肩绕渗监测系统的建议。In order to explore the seepage of the dam foundation, monitoring system of piezometer is arranged in over- burden foundation on the premise of no-measuring weir. The dam foundation seepage calculation formula of the ehannel is derived in Sandaowan hydropower station by using hydraulic gradient method, which meets the error requirement. The calculation of average seepage in flood season of 2012 is 58.06 L/s. Based on the influencing factors of dam seepage, the suggestion of adding monitoring system of by-pass seepage in abutment is put forward.
