基于静力特征的面板堆石坝设计方案比选研究

Study on design scheme selection of face rockfill dam based on static characteristics

混凝土面板堆石坝具有安全性、经济性以及地形条件适应性方面的突出优势,是水利工程建设领域的首选坝型。文章以和尚沟水电站为例,通过有限元仿真计算,对两种不同的面板堆石坝设计形式进行对比分析,结果显示,镶嵌混凝土面板堆石坝的沉降幅度大幅减小,顺坡向应力和挠度均有显著改善,建议在大坝设计时采用。

Concrete face rockfill dam has prominent advantages in safety,economy and adaptability to topographic conditions,and is the preferred dam type in the construction field of hydraulic engineering.Taking the Heshanggou Hydropower Station as an example,two different design forms of face rockfill dam are compared and analyzed through the finite element simulation calculation.The results show that the settlement range of the dam with inlay concrete face rockfill dam is greatly reduced,and the stress and deflection along the slope are significantly improved,which would be recommended in the dam design.
