摘要
拉萨河特大桥主桥采用(36+72+108+72+36)m五跨三拱连续梁钢管混凝土拱组合结构体系。着重介绍主桥空间动力和稳定性分析,探讨了双肋拱桥横向、竖向联结系的比选优化等。
The main bridge of Lhasa River Bridge is designed as a hybrid structure system of 5-span, 3-arch continuous girder and concrete-filled steel tube arches with span arrangement (36+72+108+72+36) m. In this paper, the spatial analysis of dynamics and stability of the bridge is mainly dealt with, and comparison, selection and optimization of lateral and vertical bracing systems of the dual arch rib bridge are studied as well.
