摘要
矮塔斜拉桥是一种兼有斜拉桥和梁式桥结构受力特性的组合结构体系,在轨道交通领域应用较少。以佛山市轨道交通三号线顺德水道矮塔斜拉桥为研究背景,对该桥的静力特性、稳定性、抗震性能、风车桥耦合振动响应、局部复杂受力等进行了分析研究。分析的结果表明:该结构体系强度及刚度满足要求,也满足铁路行车安全及舒适性要求,可应用于轨道交通领域,研究成果和方法可为同类型轨道交通领域桥梁设计提供参考。
Low tower cable-stayed bridge is a new type of rigid and flexible bridge between rigid girder bridge and flexible cable-stayed bridge.Taking the Foshan City Rail Transit Line 3 Shunde Waterway short-tower cable-stayed bridge as the research background,the static characteristics,stability,seismic performance,windmill-bridge coupling vibration response,and local complex forces were analyzed and studied.The results show that the strength and rigidity of the structure can meet the requirements of railway safety and comfort,and can be applied to the low tower cable-stayed bridge in the field of rail transit.
