双幅不等跨近距离同步转体刚构桥施工关键技术研究

Research on Key Construction Technology of Double Unequal Span Short Distance Synchronous Swivel Rigid Frame Bridge

结合青岛南进场路转体桥工程,通过对双幅不等跨近距离同步转体刚构桥的研究,形成了球铰系统、不等跨称配重方案、防倾覆措施和防碰撞措施等关键部位的技术研究成果,总结的经验可为类似工程提供借鉴。

Combined with the swivel bridge project of Nanjinchang road in Qingdao,through the research of double unequal span short distance synchronous swivel rigid frame bridge,the technical research results of key parts such as ball hinge system,unequal span weighing-balancing scheme,anti overturning measures and anti-collision measures are formed.The experience summarized can provide reference for similar projects.
