| Abstract: | The dynamic calculation model about interaction between tunnel structure and surrounding rock was built by finite difference method.The influence of some factors on the dynamic response of tunnel structure with train vibration was analyzed,such as surrounding rock conditions,train velocity,the design parameters of tunnel base structure,the situation of foundation base and so on.The results show that the structure dynamic responses increase with the improvement of the level of surrounding rock;the increase o... |
