摘　　要：结合面板堆石坝设计规范的修编工作,总结分析了"5.12"汶川地震中紫坪铺面板堆石坝的震害特征,获得了关于面板堆石坝抗震措施的若干启示,包括坝顶及其附近坝坡的防护、面板垂直缝的抗挤压措施和水平施工缝的抗震设计、面板堆石坝的地震变形控制及基于抗震计算和工程经验确定抗震措施的重要性等,对做好面板堆石坝抗震措施具有重要意义。With the surveys and analysis of earthquake-induced damage of Zipingpu concrete facing rockfill dam （CFRD） during the 5.12 Wenchuan earthquakes, some inspirations from seismic damage of the dam for reinforced measures of CFRD are summarized. It mainly contains that protection of dam crest and nearby dam slope, the measurements of anti extrusion for the vertical joint, aseismic design of horizontal joint, control of earthquake-induced deformation for CFRD, choosing aseismic measures based on seismic analysis. Therefore, it is of important value to determine the reasonable reinforced measures for CFRD based on these inspirations.
