摘要
广州地铁21号线高架段典型桥梁采用了(4×40)m单薄壁连续刚构结构,在轨道交通桥梁中颇具特点,发扬了无支座设计和排水管内敷的优点。山田站为双岛四线站,站前为4线3幅桥梁,经比选,采用了(3×30)m分幅刚构配门式墩方案。
The(4×40)m single thin-walled continuous rigid frame structure is adopted in the elevated section of Guangzhou metro line 21.It has some characteristics in the rail transit bridge,and has the advantages of no bearing design and internal drainage pipe application.Shantian Station is a double-island four-line station with three bridges in front of the station.After comparison and selection,the scheme of portal pier with(3×30)m framed rigid frame is adopted.
