摘要
莆田城港大道跨木兰溪大桥主桥是两跨简支的双肋下承式钢箱拱肋结合梁桥面系的异型系杆拱桥,2跨跨径均为72m。介绍大跨径异型系杆钢拱桥吊装施工技术,对钢结构拱桥安装的主要受力杆件进行计算,可供同类吊装施工参考和借鉴。
Putian Mulan River Bridge, which is a part of city harbor road, is a two span simply-supported dual-rib lower bearing steel arch bridge with irregular-shaped tied pole system and steel box arch beams and both span are 72 meter. The paper introduces the construction of hoisting and installation of main bridge of Putian Mulan River Bridge and the calculations of forces of the main bearing tied poles during installation in the bridge, which could be helpful for construction of similar projects.
