RESEARCH ON GEOMETRIC DEFORMATION MONITORING OF STEEL TRUSS ARCH RIB APPLIED TO GUANGZHOU XINGUANG BRIDGE
On the basis of construction control of Xinguang Bridge, scheme on deformation monitoring of the steel arch rib of the three spans arch bridge that is the first to adopt composite structure that combines reinforced concrete V type rigid frame and steel truss arch in the world at present is put forward in this paper. In order to find out actual deformation of the arch rib during construction, it was monitored by use modern geodetic instrument and technology on the site, deformation parameters and characteristic of the arch rib are received, it is found that they fit well by comparing actual results with simulated ones. It is concluded that the proposed scheme is correct and feasible, and monitoring results are helpful to the optimal design and construction of similar project.
