摘　　要：为实现碳达峰、碳中和目标,我国拟规划建设一批以沥青混凝土面板堆石坝为挡水构筑物的抽水蓄能电站。但目前强震下此类工程的变形模式和极限抗震能力研究严重滞后于工程实践。本文基于动力弹塑性整体变形分析、局部滑移量数值分析研究,阐明了强震下沥青混凝土面板堆石坝强震变形规律及模式,基于坝顶震陷率、坝坡滑移量、面板拉应变3项指标评判了某沥青混凝土面板堆石坝的极限抗震能力。研究成果可为同类沥青混凝土面板堆石坝变形模式及极限抗震能力评价研究提供参考。In order to achieve the target of carbon peak and carbon neutralization,a batch of pumped storage power stations with asphalt face rockfill dams as water retaining structures are planned to be built in China. However,the research on the deformation mode and ultimate seismic capacity of dams under strong earthquakes is seriously lagging behind the engineering practice.Based on the numerical analysis of elastic-plastic deformation of earth-rock dam systems and localized slip of dam slope,the failure evolution law and mode of asphalt face rockfill dam under strong earthquake are explored in this paper,and the ultimate seismic capacity of an asphalt face rockfill dam was evaluated based on three indexes :earthquake subsidence rate,dam slope slip and panel tensile strain. The research results can provide important reference for similar projects to explore deformation patterns and evaluation of ultimate seismic capacity.
