Monitoring and Measuring Technology for Erection of Beam and Arch of Through Type Reticulated Tied-Arch Bridge
The structural design of through type reticulated tied-arch bridge without horizontal thrust has been widely used in recent years,and the mesh layout of its cable plane is more in line with people's pursuit of beauty.In the construction process,the length and angle of the cable system after the bridge is completed are the main control items of the superstructure construction,so the mileage positioning of the steel box girder and the linear control of the steel arch rib are the key points of monitoring and measurement.Based on the monitoring and measurement technology in the whole construction period of the Qilu Yellow River Bridge Project,the key points of the erection of steel box girder and steel arch rib of the through arch bridge with network structure system are briefly discussed in the paper,providing reference for the monitoring and measurement of similar bridges in the future.
