摘要
以龙塘河大桥为工程背景,介绍了大跨度钢筋混凝土箱形拱桥主拱圈的施工技术,特别是缆索吊装系统、钢拱架的悬臂拼装、主拱圈的混凝土浇筑、主拱圈施工监控等。对于施工类似拱桥具有一定的借鉴意义和工程实用价值。
Taking Longtang River Bridge as the engineering background,the author introduces the construction technology of long span reinforced concrete box arch bridge,especially the cable hoisting system,cantilever assembly of steel arch,concrete pouring of the main arch ring and the construction of the main arch of monitoring. Hopes to make reference for the similar bridge construction and practical value in engineering.
