| 摘 要： | 坝基排水孔中带出析出物是普遍的现象，通过对一批大坝析出物的化学成分、矿物组成、物化性质、微观结构和粒度组成的分析研究，结合渗流分析，论证了析出物与坝基红层、化学灌浆帷幕、坝基软弱夹层（断层），以及坝基管涌的关系．分析结果表明，沉积在排水孔口附近和排水沟内的颜色不一的杂质，多为基岩裂隙中铁、锰、钙质受地下水溶蚀后带出的，排出量甚少，目前不会危及到坝基的安全稳定．

| Abstract: | It is a common phenomenon for drain holes of dam foundation to flow out sludge. Based upon the study and analysis on chemical composition, mineral material conposition, physlcal-chemical features, mincrostructure and granularity composition of the sludge, in combination with seepage analysis, this paper demonstrates the relationships of sludge with red bed of dam foundation, chemical grouting curtain, incompetent bands(faults) and piping of dam foundation. Solves some ma jor problems involved safty stability of dam foundation. |
