SCHEDULING METHOD OF OPERATION MANAGEMENT OF RAILWAY BRIDGE

摘要

PROBLEM TO BE SOLVED: To provide a scheduling method of operation management of a railway bridge capable of properly carrying out an examination and an estimation of the structure performance of a bridge using measurement data of acceleration response of the bridge when a train runs thereon, and capable of establishing a future maintenance management schedule and an operation schedule.SOLUTION: The scheduling method of operation management of a railway bridge includes the steps of: assuming a train as a moving load train and a bridge as a simple beam, formulating a theoretical analysis model of dynamic response of the railway bridge when the train runs thereon; measuring acceleration of the bridge when the train runs thereon; estimating an unknown parameter of a theoretical analytic model from the acceleration data using an inverse analysis method; calculating a margin with respect to a reference preset by carrying out re-analysis while changing the estimated parameter of the theoretical analytic model; and establishing a management operation schedule depending on the margin.SELECTED DRAWING: Figure 32
