Due to the frequent storage and discharge cycle of the reservoir, the cushion of the face rockfill dam of pumped storage power station should have good drainage performance, but when the face slab appears cracks, the cushion with low fine particle content may have the problem of seepage stability. Taking the concrete face rockfill dam of a pumped storage power station as an example, the inverted filtration test and seepage calculation and analysis were carried out, focusing on the filter protection mechanism of cushion material and transition material. The allowable crack width of the face slab was determined according to the damage slope of cushion material. The results show that after properly optimizing the fine particle content of cushion and transition material, the requirements of inverted filtration criterion can be met, and the allowable crack width of the panel is increased by 30% on the premise of ensuring the seepage stability of cushion.

由于水库频繁的蓄泄循环作用,抽水蓄能电站面板堆石坝垫层应具有良好的排水性能,但当面板出现裂缝时偏低细粒含量的垫层可能存在渗透稳定问题。以某抽水蓄能电站混凝土面板堆石坝为例,开展反滤试验和渗流计算分析,重点研究垫层料和过渡料的反滤保护机制,并根据垫层料的破坏坡降确定面板的允许裂缝宽度。结果表明,适当优化垫层和过渡料的细粒含量,可满足反滤准则要求,并在保证垫层渗透稳定的前提下将面板的允许裂缝宽度提高30%。

由于水库频繁的蓄泄循环作用,抽水蓄能电站面板堆石坝垫层应具有良好的排水性能,但当面板出现裂缝时偏低细粒含量的垫层可能存在渗透稳定问题。以某抽水蓄能电站混凝土面板堆石坝为例,开展反滤试验和渗流计算分析,重点研究垫层料和过渡料的反滤保护机制,并根据垫层料的破坏坡降确定面板的允许裂缝宽度。结果表明,适当优化垫层和过渡料的细粒含量,可满足反滤准则要求,并在保证垫层渗透稳定的前提下将面板的允许裂缝宽度提高30%。

Due to the frequent storage and discharge cycle of the reservoir, the cushion of the face rockfill dam of pumped storage power station should have good drainage performance, but when the face slab appears cracks, the cushion with low fine particle content may have the problem of seepage stability. Taking the concrete face rockfill dam of a pumped storage power station as an example, the inverted filtration test and seepage calculation and analysis were carried out, focusing on the filter protection mechanism of cushion material and transition material. The allowable crack width of the face slab was determined according to the damage slope of cushion material. The results show that after properly optimizing the fine particle content of cushion and transition material, the requirements of inverted filtration criterion can be met, and the allowable crack width of the panel is increased by 30% on the premise of ensuring the seepage stability of cushion.
