太原至澳门高速公路广东顺德碧江-中山沙溪段所跨水道河渠和道路众多,全线桥梁总长占路线总长71.2%。主要介绍板沙尾特大桥、容南特大桥、吉昌特大桥、永胜特大桥的桥型布置,主要材料,桥梁防裂、防撞设计及桥面排水系统设计情况。该4座桥梁的跨径范围基本涵盖了常见的连续梁、连续刚构跨径,这4座桥梁的设计过程中恰逢04版桥规施行,并严格按其规定设计,对其主要构造尺寸和主要材料用量等指标进行了统计,并与采用85版桥规进行设计的桥梁的相应参数进行了对比。
Taiyuan to Macau Expressway Shunde, Beijing Bijiang - Zhongshan Shaxi section of the canal and many roads across the channel, the total length of the bridge accounted for 71.2% of the total length of the route. It mainly introduces the bridge layout, main materials, cracking prevention and anti-collision of bridges, design of bridge deck drainage system of Ban Shawei Bridge, Rongnan Bridge, Jichang Bridge and Yongsheng Bridge. The span of the four bridges basically covers the common continuous beams and the continuous rigid frame span. The design of the four bridges coincides with the implementation of the version 04 bridge gauge and is strictly designed according to its provisions. The main structural dimensions And the amount of the main material and other indicators of statistics and compared with the corresponding parameters of the bridge designed using the 85 version of the bridge gauge were compared.
