摘要
水闸闸墩裂缝问题已经严重影响水工建筑物结构稳定和安全.以某裂缝群力闸为对象,对其进行健康监测和除险加固设计,并以ANSYS Workbench有限元计算软件进行仿真分析.结果表明,裂缝宽度与其水面接触情况相关,加固措施下的闸墩和内部灌浆材料在降幅温度差幅为4℃时的最大拉应力分别为 0.45 和 0.08MPa,钢板结构能较好满足抗拉强度.研究提出的设计思路能为裂缝水闸的运维安全提供参考依据,保障水利工程的正常维护.
Abstract
The problem of cracks in the piers of water gates has become an important issue that troubles the stability and safety of hydraulic structures.In view of this,the study focuses on the health monitoring and reinforcement design of a certain crack group power gate,and uses ANSYS Workbench finite element calculation software for simulation analysis.The results show that the crack width is related to the contact situation with the water surface.Under the reinforcement measures,the maximum tensile stress of the gate pier and internal grouting material at a temperature difference of 4℃is 0.45 and 0.08MPa,and the steel plate structure can better meet the tensile strength.The design ideas proposed in the study can effectively provide reference for the operation and maintenance safety of crack water gates,ensuring the normal maintenance of water conservancy projects.
