摘要
鉴于近年来国内发生多起桥梁倾覆事故的严峻形势,交通管理部门对运营中的桥梁尤其是曲线梁桥纷纷开展抗倾覆性能的核查工作。文中以东莞市G107涌头立交Q匝道桥为研究对象,该桥为带独柱固结墩小半径多跨曲线连续箱梁桥,综合考虑抗倾覆验算的各方面要求及适用条件,运用桥梁结构有限元分析程序Midas Civil建立相应的力学分析模型,对其抗倾覆性能进行分析研究,得出相应的结论,为同类桥梁的设计和养护提供参考。
In view of the severe situation of many bridge overturning accidents in recent years in China,the verification of anti-overturning performance of bridges,especially of the curved girder bridges in service,have been carried out by the traffic administration department.This paper,taking the Q ramp bridge of Chongtou Interchange in G107as a case study,studies the small radius multi-span curved continuous box girder with single-column pier.On the basis of full consideration of the requirements and application conditions of anti-overturning checking methods,a mechanic alanalysis model is built with Midas Civil Program to study and analyze the bridge's anti-overturning performance and reach the corresponding conclusion.This study can provide useful engineering reference for the design and maintenance of similar bridges.
