介绍了四川省三台县团结水库大坝渗流观测系统自1993年7月至1999年6月的观测资料分析成果。资料分析结果表明:大坝渗流监测系统改造7年来,运行情况良好。本文建立的多因子统计模型,基本反映了大坝的实际渗流状态,可以用来预报和检验测点水位。坝体填筑土料不均匀性很大,水平向渗透性是垂直向的6倍以上。0—330和0—250两断面下游测点的位势有逐年上升的趋势;0-170和0-250坝轴上游侧坝体内位势较高且逐年上升;右副坝的坝基灌浆效果不明显。 The results of observation data analysis of the seepage observation system of Tuanjie Reservoir in Santai County, Sichuan Province from July 1993 to June 1999 are introduced. Data analysis results show that: dam seepage monitoring system transformation 7 years ago, the operation is good. The multi-factor statistical model established in this paper basically reflects the actual seepage status of the dam and can be used to predict and test the water level at the measuring point. The inhomogeneity of the dam body filling material is very large, the horizontal permeability is more than 6 times vertical. 0-330 and 0-250 two sections of the downstream point of the potential trend has increased year by year; 0-170 and 0-250 dam upstream dam high potential and rising year by year; right dam dam foundation grouting effect is not obvious.
