Arch bridge cable adjusting method
The invention discloses an arch bridge cable adjusting method. A base point of the bridge floor height is determined, and a base point position Beidou GNSS displacement measuring system is fixedly installed at the base point; an arch rib displacement Beidou GNSS measuring system and a bridge floor displacement Beidou GNSS measuring system are installed at the upper ends and the lower ends of two cables to be adjusted on the arch rib and the bridge floor respectively, and a fixed position Beidou GNSS measuring system is installed at the bottom end of a cable adjacent to the bridge floor displacement Beidou GNSS measuring system. and the arch rib displacement Beidou GNSS displacement measuring system and the bridge floor displacement Beidou GNSS measuring system at the base point are used for measuring the elevation of the cable arch rib and the elevation of a cable beam in real time. According to the arch bridge cable adjusting method disclosed by the invention, cable adjustment in construction is carried out by taking the principle bridge floor elevation control as a main part and cable internal force control as an auxiliary part; by means of the construction mode, it can be guaranteed that the bridge cable force reaches the design required value, and meanwhile the construction requirements of overall synchronous tensioning and synchronous cable adjusting of the cable arch bridge can be met.
本发明公开一种拱桥调索方法，公开了确定桥面高度的基点，在基点处固定安装基点位置北斗GNSS位移测量系统；拱肋和桥面在待调索的两根吊索上下两端处分别安装拱肋位移北斗GNSS测量系统和桥面位移北斗GNSS测量系统，与桥面位移北斗GNSS位移测量系统相邻的吊索底端安装已定位置北斗GNSS位移测量系统；通过基点位置拱肋位移北斗GNSS位移测量系统和桥面位移北斗GNSS测量系统实时测量吊索拱肋高程和吊索梁高程，本发明公开的拱桥调索方法以桥面高程控制为主、吊索内力控制为辅的原则进行施工调索，这种施工方式不仅能保证桥梁索力达到设计要求值，同时能够满足吊索拱桥吊索的整体同步张拉和同步调索的施工要求。
