【摘要】 针对中小跨径预应力混凝土连续梁桥的结构特性,提出了基于远程监测数据的桥梁状态评估方法。结合有限元模型,利用插值拟合准则,对实桥埋设的应变传感器进行了优化布置。建立数据采集及监控评估系统,对桥梁进行长期跟踪观测,实时了解被监控桥梁的状态,并对其安全性能进行评估。更多还原

【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 and evaluation system.更多还原
