均质土坝特别是砂坝,在无排水设施情况下浸润线和逸出点高,对下游坝坡强度稳定和渗透稳定很不利.提出一种管式排水系统,可作为坝体的一种排水型式.通过电模拟试验系统研究了布设方案,通过浸润线、等势线和电流量测结果分析,总结了此设施浸润线特征、排渗效果和影响因素,提出合理的布置高程、滤水管排数、位置和管径.成果在实际工作中应用,取得明显效果. Homogeneous earth dam, especially sand bar, has high infiltration line and escape point in the case of no drainage facilities, which is unfavorable to the stability of strength and infiltration stability of the downstream dam. A pipe drainage system is proposed as a kind of dam Drainage type.The layout plan was studied by the electric simulation test system.The characteristics of the infiltration line, the infiltration effect and the influencing factors were summarized through the analysis of the infiltration lines, the equipotential lines and the current measurement results, and the reasonable arrangement of the elevation, Row number, location and diameter of the results of the practical application of work, and achieved significant results.
