| 摘 要： | “500”水库是四面筑坝而成的典型的大型平原水库，大坝是建在粉质壤土地基上的碾压式均质土坝。大坝采用坝体作为防渗体，坝基采用截水槽防渗，坝体内部设“L”形排水体与下游坡脚排水棱体相接。为监测大坝及涵洞的渗流状态，在上述部位布置有161支钢弦式孔隙水压力计。本文通过对坝体渗流、坝后渗流量、坝后地下水位埋深的监测情况进行阐述，对“500”水库坝后渗水原因进行简要分析与评价。

| Abstract: | ＂500＂ Reservoir is a classic large-scale plain reservoir damming from all sides. The dam is the gr/nding homogeneous earth dam constructed on the silt loam. The dam adopts the body as the impervious element, the dam base adopts cut off trench seepage control, and the ＂L＂ shape drainage body inside the dam connects to the downstream toe drainage prism. 161 string wire pore water pressure gauges are arranged in above areas in order to supervise the seepage of dam and culvert. This paper briefly introduces and evaluates the reasons of dam seepage of ＂500＂ through elaborating the supervision situations on dam body, dam back seepage flow and dam back underground water level buried depth. |
