Abstract
On Prediction of Road Traffic Vibration of INCE/J Technical Subcommittees, we are studying the creation of prediction formulas for vibration from embankments and cuts and vibration from bridges. This paper presents the concept of a simplified method for predicting road traffic vibration from viaducts. When large vehicle runs on viaduct, vibration occurs in the floor slab and propagates from the piers and foundation to the ground. Here, the reference waveform at the bottom of the pier is used as the reference point unit pattern, and the vibration propagates from the bottom of each pier on the plane to the ground surface, and a method of calculating the combined value at the prediction point is considered, and the establishment of a prediction method is examined. bottom. In addition, we will report on the results of an attempt to predict the vibration propagation situation to the surroundings for a large vehicle test run and compare it with the actual measurement value. In addition, we examined the calculation procedure assuming traffic flow conditions in this model.
