三跨中承式钢箱系杆拱桥力学计算分析与施工控制
Measurement Control for Construction of Three-span Center-bearing Steel Box Tie Arch Bridge
摘要
Abstract
Taking a three-span medium-bearing steel box-tie arch bridge with a span arrangement of 30 m+130 m+30 m as an example,the stress state and key technology of construction control of the three-span medium-bearing steel box-tie arch bridge is analyzed and researched from various perspectives,such as the establishment of the finite element model,structural analysis of the key parts,calculation of the structural prearchedness,and line control,etc.The measurement methods of the corresponding parameters are put forward,and the con-struction of the bridge is monitored and analyzed with comparison with the on-site measurement data.The whole process control method was used to monitor the construction of the bridge,and compared and analyzed with the on-site measured data,and the results showed that the force state and line shape of the bridge during construction and after completion of the bridge were the same as the control target.关键词
