On design for main bridge of Jing'an Secondary Bridge

结合井岸二桥场地地质条件及该桥技术标准,从箱梁构造、预应力钢束、下部构造三方面介绍了主桥结构设计,并对其进行了结构受力分析,提出了设计措施,以避免出现弊病,保证大桥安全、高效地运营。

Combining with the geological condition and technological standard of Jing＇ an Secondary Bridge, the paper from box girder, pre- stressed steel strand and lower structure, introduces the structural design for main bridge, has the structural stressed analysis, and points out the design measures, so as to avoid the shortage and ensure the safety of the bridge and its effective operation.
