摘要：
A model to predict the relative deflections of the bearings used at the ends of a viaduct has been derived. The predicted responses are in excellent agreement with the measured results using eddy probes. The onset of deflections is clearly detected, and significant reflections are obtained only when a train is passing through the viaduct. The amplitude of deflection when a train is on the viaduct is of an order or two higher than the ambient. This technique shows great potential in assessing rite elasticity of the elastomeric material used in the beatings. Copyright (C) 1996 Elsevier Science Ltd
