上海轨道交通3号线综合改造工程宝山路站桥梁工程总体设计

宝山路站综合改造工程是上海轨道交通3号线综合改造工程＂两站一区间＂改造范围内的节点工程,涉及土建及系统类众多相关专业,工程内容十分复杂,目前在国内外尚无同类工程实施先例。尤其重要及困难的是,在针对高架站实施改造的全过程中需确保轨交3、4号线的安全运营及车站的正常使用。总体设计中,针对宝山路站北侧新增股道创造性地实现了在既有高架站屋内进行新建桥梁设计;针对南侧新增股道,紧邻既有站屋新建桥梁设计了跨越铁路站场股道的异形门式墩。

Overall Design for the Viaduct Engineering at Baoshanlu Station for Shanghai Transit Line 3 Comprehensive Rehabilitation
