本文从原型观测资料、填筑土料同基岩接触面抗渗强度的室内模拟试验以及渗流计算三方面进行了陆浑大坝安全分析。结果表明:目前大坝的运行状态是正常的,水库在缓慢蓄水过程中,截水槽原施工中存在的薄弱地带可以得到渗透加固,截水槽中的填土与岩石结合面的抗渗比降均可达50以上,为设计洪水位下可能出现的水力比降的7.4倍。大坝今后有条件投入正常运行。

On the basis of the prescribed hydrogeological model, using the method of mathematical statistics and numerical simulation, the paper successfully solves the dam foundation seepage problem perplexing the normal operation of the reservoir. It obtains the knowledge of the stability condition of the dam foundation seepage and its changing tendency. This study manifests that the present operating condition of the dam is in normal state. During the slow water storing process of the reservoir, the weak portion of the cut-off trench can be solidified due to seepage. The piping resistance of the junction of the fill and rock in the trench rises up to 45. The upstream blanket and the combination of the cut-off trench with the downstream drainage effectively controls the dam foundation seepage system. In this way, it presents the theoretical basis for the reservoir to be set at the normal high water level(319.5m, 327.5m, 331.8m) operation.

Luhun Reservoir lies in the middle reaches of Yi River, Songxian County, Luoyang City, Henan Province, China. The authors have analyzed the water-level observation references for the past over 30 years, and determined the qualitative analysis of the hydrogeological models. On this basis, this paper presents, in line with the principle of modern mathematical statistics, a successful solution to the seepage in the dam foundation that has prevented the normal operation of the reservoir. This solution deepens our understanding of the seepage stability and its changing pattern for the dam foundation, in order to secure the normal operation of the dam when the reservoir reaches its normal high water levels (319.5 m, 327.5 m, 331.8 m).The research results show that the present operation of the dam is normal, that the weak parts of the cut-off trench can be consolidated during the slow storage of water in the reservoir, and that the seepage resistance rate at the interface between the soil fill and the rocks in the cut-off trench may reach over 45. The seepage-proof system consisting of the blanket in the upper reaches and the cut-off trench combined with the drainage in the lower reaches has effectively controlled the seepage in the dam foundation. At the same time, the seepage in the dam foundation when the water level is high is forecasted to be stable, so that the reservoir can be put to operation when the water level in the reservoir is high, providing an example of the proof of a defective and dangerous reservoir.
