Abstract
A certain thickness of thawing soil remains after the construction of subway tunnel by the artificial freezing method in soft soil area. The physical and mechanical properties of soil change a lot after freezing and thawing; therefore, the dynamic response of thawing soil is different from that of undisturbed soil under the same vibration loads of subway. The numerical simulations of thawing soil and undisturbed soil were conducted in this paper. The variations of the acceleration and the displacement of the surface and some special points were analyzed. The propagation characteristics of wave in the soil and the differences between thawing soil and undisturbed soil were obtained.
