册田水库主坝塑性混凝土防渗墙防渗效果及其渗透稳定性分析

Analysis on Seepage Prevention Effects and Seepage Stability of Plastic Concrete Cut-off Wall of the Main Dam of Cetian Reservoir

主坝塑性混凝土防渗墙工程是册田水库除险加固工程的重要项目,通过防渗墙体施工质量检测以及渗流监测,对水库除险加固后主坝防渗效果及其渗透稳定进行多种方法的分析和评价,结果表明塑性混凝土防渗墙防渗效果明显,有效地解决了主坝渗流稳定存在问题.同时针对在分析中发现的问题,对水库的运行管理提出进一步的要求.

The plastic concrete cut-off wall of the main dam is an important project for the reinforcement project in the Cetian Reservoir.By inspecting the construction quality and monitoring the seepage prevention effect of cut—off wall,the paper analyzes and evaluats the seepage prevention effect and seepage stability of the main dam after the reinforcement of reservoir by sereral methods.The results show that the seepage prvention effect of plastic concrete cut--off wall is obvious,which effectively solves the problem of seepage stability of the main dam.At the same time,according to the problems found in the analysis,further requirements are put forward for the operation management of the reservoir.
