广三铁路联络线珠江东、西桥位于广州市区,为公铁两用桥,中间双线铁路(现仅使用一线),两侧为公路单车道,是目前广州市与芳村工业区及向佛山以西方向出入的唯一公路通道。随着经济改革开放,公路运量猛增,造成该地段公路交通严重堵塞。为解决这一问题,经铁路有关部门认真研究,同意将珠江东、西桥铁路预留线暂时改铺汽车道,以缓和公路交通紧张状况。自1987年9月底铺成至今,取得了很好的效果。本文扼要介绍了铁路桥改铺汽车道的设计与施工,并对近期与远期、安全与效益、使用与维护等方面所采取的技术措施进行了论述。
Guangzhou-Sanjiang Railway The connecting line Pearl River East and West Bridge are located in the urban area of Guangzhou. They are dual-purpose railroad and railway bridge, middle double-track railway (now only use first-line railway) and single lane road on both sides.
