Application of Global Positioning System Measuring Technology in Safety Monitoring of Long-Span Bridges
With the application of Global Positioning System (GPS) echnology using in the field of modern transport, more and more long-span bridges have set up the GPS system to monitor the real-time deformation in safety monitoring system. Nowadays the highest measuring accuracy of GPS technology achieves millimeter, and the sampling frequency can reach 20Hz. It can solve real-time deformation data and adapt to the complexity and poor working environment. Based on the application of GPS technology using in long-span bridges safety monitoring system, this paper set the Huangpu bridge as the engineering project and demonstrate how to apple the GPS technology in deformation monitoring and security evaluation.
