GPS displacement monitoring system of Pingsheng Bridge

Displacement monitoring is an important part of long term health monitoring system of Pingsheng Bridge.lt is essential for evaluating health condition and stress performance. The paper is combined with norms to build health monitoring finite element model of Pingsheng Bridge, it takes into account the influence of environmental changes such as temperature, humidity, wind speed and the like on the alarm value, and fits the displacement alarm value formula considering environmental change, Pingsheng Bridge Health Monitoring displacement monitoring system is established through combining with characteristics of GPS RTK, the system is processed according to the measured data, thereby realizing real time alarm of bridge line shape health state.
