摘要:
昭平台水库溢洪道建成于1970年,在运行过程中,溢洪道闸墩支座梁附近产生了贯穿性裂缝.溢洪道作为水利枢纽中的主要建筑物,其本身的可靠性是枢纽安全的重要保证,因此有必要找出溢洪道闸墩裂缝的成因,并分析带裂缝运行的闸墩是否安全、稳定.对昭平台水库溢洪道闸墩进行非线性有限元分析,成功地模拟了裂缝扩展,探讨了闸墩支座梁附近混凝土开裂的原因,提出了改进措施.计算分析成果已为工程所采用.
Abstract:
The spillway of the Zhaotai Reservoir was completed in 1970, and during operation, a penetrating crack was created near the support beam of the spillway pier. As the main building in the water conservancy hub, the reliability of the spillway itself is an important guarantee for the safety of the hub, so it is necessary to find out the cause of the crack in the spillway pier and analyze whether the gate pier running with crack is safe and stable. The nonlinear finite element analysis of the spillway pier of Zhaotai Reservoir successfully simulated the crack propagation, the causes of concrete cracking near the gate pier support beam were discussed, and improvement measures were proposed. The results of calculation and analysis have been adopted for engineering.
