曲线变截面波形钢腹板连续梁桥钢腹板安装控制技术

Installation Control Technology of Corrugated Steel Webs with Curves and Variable Cross Section Continuous Girder Bridge

由于波形钢腹板的刚度较小易变形,其准确定位安装精度要求高,特别是在曲线变截面桥梁施工中,控制难度非常大,对桥梁质量控制起着极其重要的作用。以实际工程案例为背景,调整了施工控制思路和方案,研发出新的定位调节装置,简化钢腹板的安装步骤,并实时监测反馈,提高了波形钢腹板准确性和稳定性。

Because of the small stiffness and easy deformation, the positioning and installation accuracy requirements of corrugated steel webs is very high. It is hard and important for the construction quality, especially in the curves and variable cross section continuous girder bridge. The thinking and scheme are adjusted, including the development of new installation control device, the simplification of installation steps, and real-time monitoring, in order to improve the veracity and stability for corrugated steel webs.
