武汉轨道交通前川线高架桥方案研究

Study on the Viaduct Schemes for Qianchuan-line of Rail Transit in Wuhan

以武汉市轨道交通前川线为工程背景,对高架区间标准段桥梁方案进行研究.基于安全可靠、适用耐久、技术先进、经济合理的设计要求,在确定桥梁结构体系和标准跨径的基础上,对梁部结构、桥墩造型和施工方法进行了重点研究,并确定合理的设计方案,可为轨道交通桥梁设计提供参考.

Taking the Qianchuan-line of rail transit in Wuhan as the engineering background,the schemes of the standard viaduct are studied.Based on the design requirements of safety,reliability,serviceability,durability,advanced technology and economic rationality,the structural systems and the standard span are determined.Based on this,the beam superstructure,the shape of bridge piers and the construction methods are mainly studied.Then,the rational design scheme is determined.These conclusions could provide some references for the bridges of rail transit.
