摘要
本文按剪切梁理论 ,采用附加质量和附加刚度的方法导出面板堆石坝自振频率和振型的计算公式 ,进而讨论了防渗面板对坝体自振频率和振型的影响 ;在此基础上 ,用振型叠加原理计算了面板堆石坝的地震反应 。
In this paper, formulas for computing natural frequencies and modes of CFRDs are derived based on the additional mass and stiffness method according to shear wedge beam theory. The influences of concrete\|face to natural frequencies and modes are discussed. Furthermore, the seismic responses of CFRDs are calculated by using the mode\|superposition scheme. The calculated results are compared with the responses of rock dams.
