Vibration Impact of Freight Train on the Tunnel Base Rock Mass
Abstract The tunnel base diseases threaten the safety of the heavy haul railway operation, one important reason is the effect of freight train vibration load. In this paper, based on the Huojialiang Tunnel on Shen-Shuo Railway Line, a dynamic-finite-element model including the rail, the tunnel structure and the rock mass was established to analysis the vibration influence on the tunnel base rock mass. The simulated 25t axle-load freight train load was applied on the sleepers. The results showed that the rock mass within 6.8 m away from tunnel invert was obviously influenced by the train vibration load. But to the rock mass just under the center of tunnel invert, the range of influence was expanded to 10 m. The rock mass out of the above range was less impacted by the freight train load.
