Method for Proposing Countermeasures against Ground Vibrations along Railway Lines Based on Numerical Simulation

Abstract

This paper introduces a new method for proposing measures to reduce train-induced ground vibration, which considers three primary factors: source, structure, and ground. In this method, the primary factor is first extracted by using a numerical simulation consisting of a running train, tracks, supporting structures and the ground. Second, candidate countermeasures targeting the primary factor are selected from a provided list. Thirdly, the vibration reduction of each countermeasure is evaluated quantitatively. Finally, based on results a countermeasure is selected.
