| 中文摘要: |
| 茅草街大桥主桥为中承式钢管混凝土系杆拱桥，主跨368m，桥面净宽仅16m，宽跨比很小．为了保证茅草街大桥主桥的稳定安全性，同时又使设计经济、合理、美观，本文建立茅草街大桥主桥的空间稳定分析模型，研究横向联系构造及主拱圈构造的不同形式对钢管混凝土拱桥稳定性的影响，得到了拱桥构造与拱桥整体稳定性之间的影响曲线，提出了茅草街大桥主桥整体稳定性优化的措施。 |
| 英文摘要: |
| The main bridge of Mcaocaojie bridge is a half-through concreted-filled steel tube(CFST) arch bridge with the ratio of width of deck(16m) and main span(368m) being very small.So its overall stability is one of the critical problems in design.To assure the stability of the main bridge and simultaneously make the main bridge economical,rational,artistic,a three-dimensional stability analysis model of Maocaojie bridge is set up,and the effects of different structure details of the horizontal joints system and the arch rib on stability are studied,then the influence curves are presented,finally the optimization measurements of the structure stability of Maocaojie bridge are given in this paper. |
