先简支后连续预应力小箱梁的优化及应用

The optimization and application of pre-stressed box girder with first simply supported and continuous

结合具体工程实例,简要介绍了在原部颁标准图的基础上根据《公路桥涵设计通用规范》和实际工程经验做出的修改及应用,从而使得预制小箱梁的应用越来越广泛,为今后类似工程提供设计、施工参考。

Combining with the specific example,this paper briefly introduced the modification and application according to＂design general specification of highway bridges and culverts＂and actual engineering experience based on the standard drawing promulgated by original department,so as to make the application of precast box girder more and more widely,provided design and construction reference for future similar engineering.
