摘要

研究目的:结合吴江单轨交通的工程实际情况，从桥梁的角度出发，研究跨座式单轨和悬挂式单轨的技术特点及适用范围，分析单轨交通的结构体系，根据不同的材料确定合适的截面形式，剖析下部结构的结构形式、构造措施以及单轨交通的施工方法，旨在找出适合吴江单轨交通的桥梁结构形式和施工工法。

研究结论:通过比较分析得出:(1)跨座式单轨交通比悬挂式单轨交通更适合吴江单轨工程;(2)从经济、施工等方面来看，简支梁结构体系优于连续梁结构体系;(3)结合景观及环保要求，桥墩和梁部推荐采用钢结构，基础采用钢筋混凝土结构，支座采用铸钢拉力支座;(4)本工程梁重约15t，墩高约8 m，推荐采用汽车吊装架设的施工方法;(5)本文研究成果适用于单线跨座式单轨交通。

Abstract

Research purposes: Combined with the Wujiang monorail project actual situation，starting from the angle of the bridge，this paper studies the straddle monorail and suspended monorail technology characteristics and scope of application，analyses the structural system of monorail. According to different materials the appropriate section form is determined. This paper studies the structure form, structural measures of the lower structure and the monorail construction method, in order to find out the bridge structure form and construction method suitable for Wujiang monorail.

Research conclusions ; Through the comparative analysis，it is concluded:(1)Straddle monorail is more suitable for Wujiang monorail project than suspended monorail. (2)From an economic and construction perspective，simply beam structure system is better than continuous beam. (3)Combining of landscape and environmental requirements，pier and beam are recommend to use the steel structure，foundation uses the reinforced concrete structure，cast steel supports are used for tension bearing. (4)Due to the beam weighing of 15 tons and pier height of 8m，the construction method using auto to hoist and erect is recommended. (5)The research results of this paper can be applied to single line straddle mon-orail transportation.
