乌拉泊水库副坝混凝土防渗墙防渗效果分析

Seepage Prevention Effect Analysis of Concrete Diaphragm Wall of Wulapo Auxiliary Dam

乌拉泊水库在利用混凝土防渗墙对主坝进行防渗处理后,解决了主坝渗流不稳定的问题,在此基础上于1999年至2002年又延长了混凝土防渗墙,对副坝进行了防渗处理。文中通过对防渗处理前后的测压管水位进行相关分析、位势分析、类比分析、防渗体有效系数分析,以及副坝排渗暗管排渗流量分析,认为副坝防渗墙防渗效果明显,有效解决了副坝渗流不稳定的问题。

By use of concrete diaphragm wall seepage prevention on the main dam of the Wulapo Reservoir, the seepage stability problem of the main dam was resolved. On this basis, from 1999 to 2002, the concrete diaphragm wall was extended and seepage prewention treatment was done for the auxiliary dam. Through correlation analysis, potential analysis, analog analysis, analysis of effective coefficient of seepage prevention and seepage analysis of underground drainage pipe for the water level of the piezometer before and after seepage prevention treatment, the conclusion is drawn that the seepage prevention for the auxiliary dam is effective, and the seepage stability problem of the auxiliary dam is resolved.
