摘要:
为了节约土地资源、提高城市交通的使用效率、改善桥梁通行条件,首次提出能使城市桥梁实现双层交通的“混凝土巨型箱形截面梁”的概念,即通过加大传统混凝土箱梁截面高度,在腹板上开设必要的孔洞,并使其顶板、底板均成为桥面系,以确保箱内外车辆通行,使城市桥梁实现双层交通的箱梁。结合工程实践介绍了混凝土箱形截面梁和城市桥梁双层交通的研究现状,并探讨了混凝土巨型箱形截面梁设计的一系列关键技术问题,填补了无横隔板、腹板大规模设置孔洞的混凝土巨型箱形梁设计技术的空白,为混凝土巨型箱形截面梁在城市桥梁中的推广应用研究提出了指导性建议。
Abstract:
The concept of “concrete huge box section girder” for achieving double-deck traffic for city bridges was first put forward for saving land resource and improving traffic efficiency and conditions of bridge passage. It referred to box girder with necessary openings in the web plates which could achieve double-deck traffic for city bridges by means of increasing the section height of the traditional concrete box girder and its roof, floor deck systems became the bridge deck system. Actual examples of the double-deck traffic were provided on an engineering practice basis and research situations on concrete box section girder and double-deck traffic for city bridges were introduced. Some key technological problems in design of concrete huge box section girder were discussed, which filled the gaps in the field of the design technology of the concrete huge box section girder without inner plate. Some guiding recommendations of the promotion applications of concrete huge box section girder for city bridges were proposed.
