摘    要:碾压混凝土重力坝采用大仓面薄层连续浇筑,其层面是一个薄弱环节,这是一常规混凝土坝的主要区别之一。“八五”期间结合仿真模型试验和非线性有限元法计算,对碾压混凝土重力坝体层间破坏的形状、位置、发生条件及其影响因素进行了研究,为设计碾压混凝土重力坝提供科学依据。

关 键 词:碾压混凝土  重力坝  破坏机理  稳定分析  水电站

Abstract:Because the continuous pouring with large working surface and thin layer has been adopted in RCC gravity dam,its bedding surface is a weak link,which is one of main distinctions from the conventional concrete dam.During the Eighth-Five- Year Plan period,the studies on the shape,position,occurrence conditions and its influence factors of the bedding surface failure in RCC gravity dam body have been conducted in combination with the simulation model test and the calculations by non-linear finite element method,which provides the scientific basis for the design of RCC gravity dam.
Keywords:RCC  gravity dam  failure mechanism  stability analysis  Longtan Hydropower Station
