为确定某平原水库溢洪闸右边墩的裂缝成因,借助有限元软件对水闸边墩进行了正常运用工况下的三维数值计算,分析了右边墩的应力、应变情况,进而通过现场试验及分析结构配筋情况,给出了右边墩的裂缝成因,即在正常运用情况下,边墩裂缝位置存在明显的应力、应变集中区域,且现有结构配筋不满足最小配筋率要求、混凝土老化严重。
In order to determine the cause of cracks in the right pier of a plain reservoir, the three-dimensional numerical calculation is carried out by using the finite element software in the normal operation of the sluice side piers. The stress and strain of the pier on the right are analyzed, and then the field test and analysis In the condition of normal operation, there are obvious stress and strain concentration areas in the crack location of the pier, and the existing structural reinforcement does not meet the requirements of the minimum reinforcement ratio and the concrete aging serious.
