桥墩桩基抗冲刷安全性分析及加固设计要点

Safety Analysis of Anti-scour of bridge pier and key points of reinforcement design

近年来河道冲刷、桥墩桩基外露的病害频发,河道冲刷严重影响桥梁桩基承载能力。以湖北省黄冈市上巴河桥为案例,探讨分析了河道冲刷对桥墩安全性的影响,在此基础上,提出了有针对性的桥墩加固方案,提高了桥墩抗冲刷安全性,并通过计算分析验证了加固方案合理性。

In recent years,river scour and pier pile foundation exposed diseases occur frequently,which seriously affect the bearing capacity of bridge pile foundation.Taking the Bahe bridge as an example,this paper discusses and analyzes the impact of river scour on the safety of bridge piers,and on this basis,puts forward targeted pier reinforcement scheme to improve the safety of pier anti scouring,and verifies the rationality of reinforcement scheme through calculation and analysis.
