摘要
湖北白水港大桥原设计为汽-20,挂-100刚架拱桥,由于要将荷载等级提高至公路Ⅰ级,需进行荷载等级提高加固设计,同时还需进行拓宽改造。重点介绍粘贴钢板加固设计方案和施工工艺,以及桥面加铺整体钢筋混凝土层及拓宽改造技术在刚架拱桥加固设计中的综合运用。
Original design for Hubei Baishuigang Bridge is rigid - framed arch bridge with truck - 20, trailer - 100. In order to increase the load capability to Grade I Road, load capability upgrading minfomement design is requested, also it needs to be broadened. This paper mainly introduces binding steel plate reinforcement design and construction processes, hying reinforced concrete layer on bridge deck and integral application of broaden technology in rigid- frame arch bridge reinforcement design.
