参窝水库溢流坝闸墩裂缝加固处理效果分析

Strengthening Effect Analysis of Sluice Pier Cracks in Shenwo Reservoir Overflow Dam

参窝水库运行以来,溢流坝闸墩出现竖向活动裂缝,危及结构安全,提出适宜的修补加固技术,并对修补加固处理后的结构采用ANSYS软件进行受力状态有限元计算分析,得出闸墩混凝土裂缝修补加固后安全可靠,裂缝不再继续扩展,工程可安全运行,继续发挥其效益。

Vertical lively cracks on sluice pier in Shenwo Resevoir overflow dam were appeared since operation, and the structural safety of dam was endangered.Suitable technology of repairing and strengthening were proposed, then strueturarl stress state of finite element eomputationaf analysis were conducted by using ANSYS software after repairing and strengthening.The results concluded that the piers were safity after repairing and strengthening for concrete crack, cracks no longer continue to expanded, and the safe operation of the project could be continued to play its role.
