分析溢洪道钢筋混凝土边闸墩的工作环境及边界约束条件的复杂性，采用空间有限元对其裂缝成因进行研究，指出环境温差是引起溢洪遣边闸墩裂缝的重要原因。
Analysis of the spillway reinforced concrete side piers of the working environment and the boundary constraints of the complexity of the finite element analysis of the causes of cracks, pointed out that the environmental temperature difference is caused by the spillway tributary pier cracks is an important reason.
