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。
Based on the analysis of the causes of the serious problems in CFRD at home and abroad, the concept of experience design of CFRD is abandoned for many decades. It is pointed out that in addition to the anti-skid stability and safety required by earth-rock dam In addition to the seepage stability and safety, deformation safety requirements must also be met. The new concept of deformation coordination for the design of high concrete faced rockfill dam is established, including the settlement coordination of the dam, the horizontal displacement coordination of the dam, the deformation of the dam body in the normal direction of the panel and the dam axis, and the synchronization of panel deformation. The connotation of the deformation safety design of the rockfill dam includes deformation coordination criteria, criteria, calculation methods and measures. Taking the 203.5 m high Bakun Dam as an example, the necessity of replacing the experience design concept with the new concept of deformation coordination design is illustrated.
