摘　　要：结合NB 35047-2015《水电工程水工建筑物抗震设计规范》,重点研究了基于规范标准设计反应谱、场地反应谱及设定地震的场地相关反应谱确定的动参数下面板堆石坝坝体的动力响应。依托于某面板堆石坝,计算了在上述三种反应谱下坝体的加速度响应、动位移、永久变形、坝坡塑性累计滑移量等指标。计算结果表明:采用设定地震的场地相关反应谱得到的坝体抗震各项指标均高于规范标准设计反应谱和场地反应谱,采用规范标准设计反应谱和场地反应谱确定的动参数进行面板堆石坝的抗震计算结果偏于保守,为面板堆石坝的抗震计算及设计提供参考。Combining with"Code for Seismic Design of Hydraulic structures of Hydropower Project NB 35047-2015",the dynamic response of CFRD under standard design response spectrum and site response spectrum and probability-consistent response spectrum is studied in detail.Take a CFRD as an example,the acceleration response,dynamic displacement,permanent deformation and cumulative plastic slip of dam slope under the above three response spectra are calculated.The calculation results show that seismic indexes of dam using probabilityconsistent response spectrum are higher than using standard design response spectrum and site response spectrum.The seismic calculation results of CFRD are conservative by using the standard design response spectrum and site response spectrum.It provides reference for seismic calculation and design of CFRD.
