黄丰水电站工程右岸土石坝采用混凝土防渗墙与复合土工膜联合防渗结构。简要介绍土石坝上游坝坡防渗体系设计、坝体整体的渗流计算、稳定计算以及复合土工膜与上下保护层料之间的抗滑稳定性分析。经计算，坝体整体渗流量相对多年平均流量较小，可忽略不计；上游坝坡采用加糙复合土工膜或设置防滑槽形式铺设，稳定性满足规范要求。
黃豐水電站工程右岸土石壩採用混凝土防滲牆與複閤土工膜聯閤防滲結構。簡要介紹土石壩上遊壩坡防滲體繫設計、壩體整體的滲流計算、穩定計算以及複閤土工膜與上下保護層料之間的抗滑穩定性分析。經計算，壩體整體滲流量相對多年平均流量較小，可忽略不計；上遊壩坡採用加糙複閤土工膜或設置防滑槽形式鋪設，穩定性滿足規範要求。

The combined impervious structure of concrete cutoff wall and composite geomembrane is applied in the earthrock fill dam on right bank of Huangfeng Hydropower Project.In the paper, design of the impervious system of the upstream dam slope of the earthrock fill dam, the integrated seepage and stability calculations of the dam body, and analysis on the stability against sliding between the composite geomembrane and both up and down protection layer materials are described.Through calculation, the integrated seepage of the dam body, compared with the average carryover discharge, is lower.It can be ignored.The roughened geomembrance is applied at the up-stream dam slope or the geomembrane is laid with trough against sliding.Specification on stability is satisfied.
