The Finite Element Analysis of Ground Vibration Induced by Subway
摘要
Abstract
Via finite element method software ANSYS,the dynamical analysis model of train-tunnel interaction is established. And effects of the tunnel structure type with pile foundations,burial depth of tunnels,and ground parameters on the ground vibration induced by subway are then analyzed. The calculation results show that the tunnel structure type with pile foundations is effective for reducing the ground vibration. The longer piles are,the better the reduction effect is. Burial depth of tunnel has great influence on ground vibration caused by subway. And the ground vibration intensity decreases as the burial depth of tunnel increases. The im-pact of ground parameters on ground vibration is related to the exciting frequency.关键词
