| 摘 要： | 李溪拦河闸坝在2000年完成了上游护坦和下游消力池、海漫等工程的改建。为了解工程改建后的防冲及防渗效果，在大坝下游设置了36个渗压观测孔，利用自动监测系统对该大坝的地基渗压情况进行长期观测：2003年6月，大坝安全监测系统建成投入运行。监测系统采集的渗压数据初步分析表明，李溪拦河闸坝的消力池、海漫、护坦等工程改造后，防冲和防渗效果良好，没有发生集中渗漏、管涌和基础冲蚀等安全隐患。

| Abstract: | Reconstruction on apron,pitching and absorption basin down stream of the Lixi gate dam which across the river was accomplished in 2002.36 drill bores for observation had been arranged for finding out the effect of protection against erosion and seepage after reconstruction,using automatic monitoring system to observe the situation of permeated peressure. A dam safety monitoring system was set up and went into operation in June,2003.The preliminary data analysis on permeated pressure indicate that the effectiveness of protection against erosion and seepage are well and hidden trouble of piping, concentrated leakage and erosion on foundation haven't occurred. |
