黄壁庄水库副坝工程自投入运行以来,坝身及上游铺盖多次发生裂缝及踏坑;下游排水沟及减压井多次发生冒沙和管涌现象。采用一种改进的层次分析法,从可靠性、耐久性、施工条件、运行管理、经济因素及环境因素六个方面对河北省水利厅提出的四种防渗方案进行综合评价。结果表明,坝顶组合垂直防渗方案为最优防渗方案。
黃壁莊水庫副壩工程自投入運行以來,壩身及上遊鋪蓋多次髮生裂縫及踏坑;下遊排水溝及減壓井多次髮生冒沙和管湧現象。採用一種改進的層次分析法,從可靠性、耐久性、施工條件、運行管理、經濟因素及環境因素六箇方麵對河北省水利廳提齣的四種防滲方案進行綜閤評價。結果錶明,壩頂組閤垂直防滲方案為最優防滲方案。

Since the secondary dam of Huangbizhuang Reservoir has been put into operation, the dam and upstream apron have happened cracks and tread-pit phenomena many times, and the sand boil and piping phenomena have occurred near the downstream drain and relief well. So four feasible anti-seepage schemes are proposed by Hebei Province Water Con- servancy Department. Here, an improved AHP are adopted to comprehensively evaluate the schemes in aspects of relia- bility, durability, construction conditions, operation management, economic factors and environmental factors. The result shows that the crest-combined vertical anti-seepage scheme is an optimal anti-seepage scheme.
