Construction method of suspended single-cable-plane cable-stayed steel bridge
The invention discloses a construction method for a suspended single-cable-plane cable-stayed steel bridge. The construction method comprises the following steps that firstly, three-dimensional modeling is conducted on a cable-stayed bridge; secondly, a temporary support system is built; 3, analyzing the overall stress of the cable-stayed bridge; 4, pedestrian comfort vibration reduction analysis on the cable-stayed bridge is carried out; and fifthly, stay cables are installed and tensioned. Aiming at the problems that a single-cable-plane cable-stayed bridge structure of a suspension system is light and small in rigidity, the pedestrian comfort degree does not meet the requirement and small-cable-force asymmetric cooperative tensioning is difficult, a finite element simulation analysis technology is utilized, the dynamic characteristics and the sensitive frequency range under different load conditions and different walking working conditions are systematically analyzed, and through arrangement of vertical and transverse TMD damping devices, the single-cable-plane cable-stayed bridge structure is obtained. And it is ensured that the pedestrian comfort reaches the optimal level, and the safety and comfort of the bridge are guaranteed.
本发明公开一种悬浮单索面斜拉钢桥施工方法，包括以下步骤：步骤一，斜拉桥三维建模；步骤二，临时支架体系搭建；步骤三，斜拉桥梁整体应力分析；步骤四，斜拉桥上人行舒适减振分析；步骤五，斜拉索安装及张拉。本发明针对悬浮体系单索面斜拉桥结构轻柔刚度小，人行舒适度不满足要求及小索力非对称协同张拉难题，利用有限元模拟分析技术，系统性分析不同荷载状况下，不同行走工况下动力特性以及敏感频率范围，通过设置竖向、横向TMD阻尼装置，确保人行舒适达到最佳级别，保障了桥梁的安全性和舒适性。
