平顶山市神马路湛河桥主桥方案设计

Scheme Design of Shenma Road Bridge crossing Zhan River in Pingdingshan

本桥位于河南省平顶山市神马路,跨越湛河。主桥采用波形钢腹板PC连续梁,跨径布置为52 m+85 m+52 m,桥面宽度40 m。介绍了该桥的工程概况、初设阶段的结构设计、施工方案,结构计算分析表明:该设计方案主要构件的各项性能均满足规范要求,采用的波形钢腹板与底板混凝土的外包型连接施工方便、耐久性好,可为波形钢腹板PC连续梁设计提供参考。

The bridge is located on Shenma road in Pingdingshan, which crosses Zhan river. The main bridge is pre-stressed concrete box-girder bridge with corrugated steel webs, which span is set to 52 m+85 m + 52 m,and the width is 40 m. The overview of the project, the design of the structure in the preliminary design stage and the construction plan were introduced. The calculation and analysis results show that the design indicators meet demands. The wrapped connection which had good durability is convenient for construction, which provides the beneficial reference for the construction about pre-stressed concrete box-girder with corrugated steel web in the future.
