摘　　要：水库运行后出现溢流坝闸墩竖向裂缝,在调查与检测基础上,运用ANSYS有限元软件及线性静力学理论,分析静水荷载、闸墩上部重力荷载、闸门开启荷载、温度荷载等组合荷载作用下对闸墩整体结构应力分布计算,分析了闸墩混凝土危险区域及裂缝成因,提出裂缝修补加固技术,为类似工程问题提供借鉴。Sluice pier vertical cracks appeared after the reservoir operated.Based on the investigation and detection ,finite element software ANSYS and Linear Static theory were employed to analyze the stress distribution of pier structure in the overall and location of the crack from the perspective of linear static on hydrostatic pressure ,upper load of pier ,opening load of sluice gates ,temperature load.The causes of the pier concrete crack were discussed ,and the repair and reinforcement technology for crack was put forward to provide reference for the similar engineering problems.
