摘要
为了解决300 m级钢筋混凝土面板堆石坝的可靠性和安全性,在面板堆石坝坝体中下部采用高模量材料代替常规堆石料填筑,形成高模量特高面板堆石坝。文章以某水电站为例,通过对比研究得出结论,高模量基础垫座特高面板堆石坝在坝体沉降和变形、面板挠度等方面较普通混凝土面板堆石坝有明显改善,为面板堆石坝向300 m级高度发展的研究提供了思路、建议和参考。
In order to guarantee the reliability and safety of 300 m-high reinforced CFRD,high modulus materials are used to replace conventional rockfills in the middle and lower sections of the face rockfill dam body to build high modulus extra-high CFRD.Taking a hydropower station as an example,the article draws the following conclusion:through comparative study,the settlement and deformation of the dam body and the deflection of the face slab of the extra-high CFRD with a high modulus foundation are significantly alleviated compared to ordinary CFRD.The study provides concepts,suggestions and references for the research on the development of 300 m-high CFRD.
