A Simplified Method to Obtain Subway Vibration Load Based on Analysis in Frequency Domain

Abstract:

To obtain reasonable subway vibration load is the key to many subway vibration problems. This paper uses a simplified method to determine subway vibration load in frequency domain analysis, based on ground vibration test induced by subway traveling and numerical simulation of soil-subway model. The operating steps are explained and one example for calculating subway vibration load is given. The result shows that this method is a certain degree of effective in analysis of ground vibration problems, since that it relies on ground vibration test. The operating steps of this method are simple, and also the method can reflect characteristic of randomness of subway vibration.
