Based on the method of nonlinear finite element, the dynamic response characteristics and fatigue life of soft rock at the bottom of the typical cross section of high speed railway are studied. The research result shows that the peak dynamic stress of the soft rock increases nonlinearly with the increase of the speed of train, and decreases nonlinearly with the increase of the depth and the strength of the soft rock. Based on the Miner accumulated damage theory, the fatigue life of the soft rock at the bottom of a high-speed railway tunnel is studied. The research has certain pragmatic value to improve our country's high-speed railway tunnel design and operation management level.
