册田水库位于山西省桑干河干流上,控制流域面积16700km~2,总库容5.8亿m~3。最大坝高41.5m,系由碾压和水中填土混合修筑成的土坝。坝址基岩为玄武岩流,有两条断层通过坝轴线,坝体底面未采取处理措施,大部直接修建在柱状节理裂隙发育阿玄武岩上。在运行中,曾发生管涌、裂缝、漏水、库区冒泡等问题,1985年进行了针对性的地质补充勘探、原型观测与资料整理、分析研究等工作,并据此提出了加固改造方案。本文着重探讨水库渗流中的几个问题。 Located in the main stream of Sanggan River in Shanxi Province, the Cettian Reservoir covers an area of ​​16700km ~ 2 with a total storage capacity of 580 million m ~ 3. The maximum dam height 41.5m, by the rolling and filling the earth into a mixed earth dam. The bedrock of the dam site is basalt flow. There are two faults passing through the axis of the dam. No treatment measures are taken on the bottom of the dam. Most of the bedrock is directly built on a basalt rock with columnar jointed and fractured development. In operation, problems of piping, cracks, water leakage and bubbling in the reservoir area have occurred. In 1985, targeted geologic supplementary exploration, prototype observation and data collation, analysis and research work were carried out, and a reinforcement and reconstruction plan was put forward accordingly. This article focuses on several problems in reservoir seepage.
