虎门二桥62.5m跨预制节段拼装PC连续刚构桥上部结构设计

Humen Bridge across 62. 5 m Segmental PC continuous rigid frame bridge design department

虎门二桥部分引桥采用了62.5 m跨预制节段拼装PC连续刚构桥的结构形式,该桥纵向预应力体系为体内束加体外束。介绍了该桥上部结构的结构尺寸、节段拼装构造形式、预应力形式和节段黏结接缝构造。并采用MIDAS CIVIL 2012专业桥梁分析软件建立全桥三维空间杆系模型,对结构进行计算,结果表明结构的应力、强度均满足规范要求。

Humen Bridge Approach uses a 62.5 m section across Segmental PC continuous rigid frame structure of the bridge, the bridge longitudinal beams prestressed system plus external beam vivo. Describes the structure size of the bridge superstructure is constructed in the form of Segmental Prestressed form and segmental construction adhesive joints. And using MIDAS CIVIL 2012 professional analysis software to build a bridge full bridge three - dimensional space truss model of the structure, and the results show that stress, strength of the structure meet the specification requirements.
