摘要

摘要: 在分析国内外高混凝土面板堆石坝出现的严重问题的原由的基础上，摒弃几十年来面板堆石坝经验设计的概念，指出高混凝土面板堆石坝除了通常土石坝要求的抗滑稳定安全和渗流稳定安全以外还必须满足变形安全的要求。建立了高混凝土面板堆石坝设计的变形协调新理念，包括坝体沉降协调、坝体水平位移协调、面板法线方向和坝轴线方向的坝体变形和面板变形同步协调，提出了高混凝土面板堆石坝变形安全设计的内涵包括变形协调准则、判别标准、计算方法和对策，以 203.5 m 高的 Bakun 坝为例，阐明变形协调设计新理念替代经验设计概念的必要性。

Abstract: Based on the analysis of causes for serious damages of worldwide high concrete face rockfill dams (CFRDs), it is indicated that the empirical design concept of CFRDs should be discarded. The deformation safety is necessary besides the stability safety and seepage safety for high CFRDs. A new deformation coordination concept for high CFRDs comprising dam settlement coordination, dam displacement coordination, dam deformation in face slab normal direction and dam axis direction synchronously coordinating with face slab deformation is established. The connotation of deformation safety design of high CFRDs including deformation coordination standards, judgment criteria, calculation methods as well as counter measures, is put forward. The necessity of replacing the empirical design concept by the new deformation coordination concept is explained through the case study of Bakun Dam, 203.5 m in height.
