马尾大桥主桥为(71+83+123.5+240+123.5+83+71)m的空腹式钢-混混合梁受力体系,结构新颖。桥型的选择综合考虑地方文化、建设影响条件等多方面因素,利用梁-拱组合受力机制,将力学和美学结合起来。设计中重点对上部结构空腹段、钢混组合段及约束体系深入研究,提出合理方案。并分别采用Midas/Civil、Ansys等软件对大桥总体及关键构件进行分析,结果表明结构设计合理。
The main bridge of Horsetail Bridge is a tensioned steel-concrete hybrid beam bearing system with (71 + 83 + 123.5 + 240 + 123.5 + 83 + 71) m, with novel structure. The choice of bridge type comprehensive consideration of local culture, construction conditions and other factors, the use of beam - arch combination force mechanism, mechanics and aesthetics together. The focus of the design of the superstructure on the fast segment, steel mixing segment and restraint system in-depth study, put forward a reasonable plan. The software of Midas / Civil and Ansys were used to analyze the overall and key components of the bridge. The results show that the structure is reasonable.
