An evaluation method of bridge state is put forward based on remote monitoring data, aiming at the structural characteristics of small and medium-span prestressed concrete continuous bridges. The placement of strain sensors was optimized in a practical bridge through interpolating fitting criterion on finite element model. To observe bridges in a long term, acquaint their state in real time, and evaluate their security performance could be realized by establishing a data collection system as well as a monitoring and evaluation system.
