钢-砼组合箱梁结构是一种新型钢-砼组合结构，在桥梁加固改造技术中具有一定优势。基于某跨线人行天桥接长实例，设计了以栓钉为剪力连接件的带钢板-砼组合桥面板的组合箱梁结构的天桥接长方案，并对其进行了有限元分析。计算结果表明，带钢板-砼组合桥面板的组合箱梁方案是一种简便有效的天桥接长加固方法，能提高结构的刚度，满足各项要求。

Steel-concrete composite box-beam is a new type of steel-concrete composite structure and has certain advantages in bridge reinforcement and reconstruction .Taking a pedestrian bridge as example , we designed a composite box-beam based on lengthening reinforcement scheme which useed steel plate-concrete composite bridge decks as shear connectors and made an analysis with finite element method .The result shows that the composite box-beam scheme with steel plate-concrete composite bridge decks is a simple and effective method for pedestrian bridge , which can improve the stiffness of the structure to meet the requirements .
