上海市徐汇景东路护渠桥设计和施工

徐汇和闵行两区间景东路护渠桥跨越原水渠,带来设计和施工的难度。主要采取以下措施:利用结构分幅减小桥梁斜交角度,用T梁降低结构吊装重量,创新性的鱼腹式结构解决桥梁梁端空间受限的问题;采用城市桥梁中并不常见的架桥机施工解决大型施工车辆不能通过原水渠的问题。通过护渠桥的设计和施工的实践,工程已施工完成,对今后类似工程具有很好的借鉴意义。

Design & Construction of Jingdong Rd. Canal Protection Bridge in Xuhui,Shanghai

Jingdong Rd.Canal Protection Bridge between Xuhui District&Minhang District in Shanghai is crossing the original canal,which brings difficulties in design&construction.The main measures are adopted as follows:using structural framing to reduce the skew angle of the bridge,using T-beam to reduce the lifting weight of the structure,innovative fish-bellied structure to solve the problem of limited space at the end of the bridge beam;using bridge erecting machine which is not common in urban bridges to solve the problem that large construction vehicles cannot pass through the original canal.Through the design&construction practice of the Canal Protection Bridge,the project has been completed,which has a good reference significance for similar projects in the future.
