摘　　要：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 causes of cracks in a plain reservoir spillway pier on the right side, the finite element software was used to carry out three-dimensional numerical calculation in normal operating condition. On the basis of the analysis of the stress and strain of the pier on the right, and then through field test and analysis of the structure of reinforcement, the cause of crack is given. The result shows that there are obvious stress strain boundaries at the crack position in normal operating condition, and the existing structure reinforcement does not meet the minimum reinforcement ratio. In addition, the concrete aging is serious.
