东谷水库大坝渗流监测资料分析

Analysis of the seepage monitoring data of Donggu earth-rock dam

根据东谷水库大坝渗流监测资料,定性分析了测压管水位变化过程、位势过程、渗漏量过程等.建立了测压管水位、渗漏量回归统计模型,定量分析了测压管水位的影响因素.结果表明,回归拟合效果较好,大坝浸润线趋于升高,渗漏量趋于减小,坝体整体渗透性降低,大坝渗流运行正常,分析结论可为东谷水库大坝渗流安全评价提供技术支持.

Based on the seepage monitoring data of Donggu earth-rock dam, this paper analyzed qualitatively the variation of the piezometric tube water level,potential and leak. The regression model of the piezometric tube water level is established and the influence factors of the piezometric tube water level is quatitatively analyzed. The results showed that the regression fitting effect is well,the saturation line of the dam tends to increase, the seepage flow tends to decrease, the overall permeability of the dam reduced and the dam seepage is normal. The analysis conclusion can provide technical support for the safety evaluation of the dam seepage of Donggu reservoir.
