Steel beam installation control method and system for cantilever construction bridge
The invention discloses a steel beam installation control method and system for a cantilever construction bridge. The method comprises the steps that the theoretical height difference between a to-be-installed steel beam and an installed steel beam and the theoretical included angle between the to-be-installed steel beam and the installed steel beam are calculated according to a pre-established finite element model of the whole bridge; the to-be-installed steel beam is pre-installed at the front end of the installed steel beam according to the theoretical height difference between the to-be-installed steel beam and the installed steel beam; calculating the front and rear end height difference of the to-be-mounted steel beam according to the theoretical included angle between the to-be-mounted steel beam and the mounted steel beam and the actually measured position information of the two; and adjusting the position of the to-be-mounted steel beam according to the calculated height difference of the front and rear ends of the to-be-mounted steel beam. The influence of factors such as temporary load and temperature is avoided, the steel beam installation error is reduced, and the steel beam installation precision and construction efficiency are improved.
本发明公开了一种悬臂施工桥梁的钢梁安装控制方法及系统,方法包括:根据预先建立的桥梁整体的有限元模型计算待安装钢梁与已安装钢梁的理论高差以及两者之间的理论夹角;根据待安装钢梁与已安装钢梁的理论高差将待安装钢梁预安装在已安装钢梁的前端;根据待安装钢梁与已安装钢梁之间的理论夹角以及两者的实测位置信息计算待安装钢梁的前后端高差;根据计算得到的待安装钢梁的前后端高差调整待安装钢梁的位置。本发明规避了临时荷载和温度等因素的影响,减小了钢梁安装误差,提高了钢梁安装精度和施工效率。
