摘要
为了确保黄河羊曲水电站混凝土面板堆石坝布置合理和工程安全,采用三维有限元软件MIDAS GTS对羊曲水电站面板堆石坝坝体进行三维有限元渗流计算,分析坝体等势面、压力水头、孔隙水压力、浸润线和浸润面等渗流要素分布情况。结果表明:坝体面板及坝基帷幕的防渗效果显著,坝区的防渗系统(坝体面板+防渗帷幕)作用明显,面板堆石坝安全、可靠。
In order to ensure intelligent layout and operating safety of CFRD of the Yangqu Hydropower Station,the 3D finite element software MIDAS GTS is used to calculate the 3D finite element seepage flow in CFRD of the Yangqu Hydropower Station and analyze the distribution of seepage elements such as equipotential surface,pressure head,pore water pressure,infiltration line,and infiltration surface etc..The results show that the seepage-control effect of the dam surface and the foundation curtain is significant,the anti-seepage system(dam concrete surface+anti-seepage curtain)in the dam area is working effectively,and the CFRD is safe and reliable.
