Abstract
Purpose
This paper aims to evaluate the dynamic response of surrounding foundation and study the vibration characteristics of track system.
Design/methodology/approach
A double-line underground coupling analysis model was established, which included two moving train, track, liner and the ground field.
Findings
Based on the 2.5D (D is diameter) finite element analysis, the influence of the important factors such as the depth of the subway tunnel, the nature of the foundation soil, the relative position relation of the double tunnel, the subway driving speed on the foundation and the orbital vibration are analyzed in this article.
Originality/value
The results in paper may have reference value for the prediction of train induced vibrations and for the research of dynamic response of ground field.
