【摘要】 随着国内外混凝土重力坝建设的蓬勃发展,很多高坝将逐步在我国各个流域上兴建,特别是在高烈度场址修建高坝,其应力分析是判断大坝是否安全的前提.通过采用有限元分析方法,研究了龙滩碾压混凝土重力坝挡水坝段在静、动力作用下应力变化规律,为类似工程设计、施工提供理论依据.更多还原

【Abstract】 With the fast development of concrete gravity dam construction,high dams will be gradually built in many river basins,especially in high intensity sites,and the stress analysis is an important index for the dam safety.By using the finite element analysis method,the rule of stress change of the Longtan RCC gravity dam block in the dam section under the static,dynamic stresses are studied,which can provide the scientific basis for similar engineering designs and constructions.更多还原
