摘要
苏只水电站工程堆石坝防渗采用混凝土防渗墙与复合土工膜联合防渗体系。论述该体系设计、防渗计算以及复合土工膜与砂砾石之间的抗滑稳定性分析过程。该工程已蓄水发电1a多,坝体渗压计的测值表明混凝土防渗墙与复合土工膜联合防渗体系质量是可靠的,防渗效果也是好的,值得在中低土坝防渗上推广应用。
The combined seepage control system of.concrete cutoff wall and composite geomembrane is applied for Suzhi rockfill dam. This paper describes the design and calculation of the seepage system and analyzes the stability against slide between the geomembrane and sand gravels. Suzhi hydropower project has been impounded and operating for more than one year. The measured values of dam osmometers show that this combined seepage control system is reliable in quality and has good impervious results, which is worth of being introduced to middle and low earthfill dams.
