| Abstract: | 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... |
