The non-linearity of material and non-linearity of member for RC station structure was considered with fiber element model. The soil dynamical non-linearity was considered by equivalent damp and equivalent shear modulus of soil in earthquake. The input wave was vertical acceleration earthquake wave and south-north horizontal earthquake wave which were recorded at 83m underground in Port Island in KOBE earthquake. The software of MIDAS was used to simulate the earthquake response and destruction process of DAKAI subway station. The earthquake damage mechanism of the DAKAI subway station was studied. The damage type of column, wall and roof was analyzed. And the conclusions were obtained as following:（1）The middle column was first damaged in earthquake, which is the weakest part in the entire underground structure； The horizontal earthquake was the main factor of （2） underground structure destruction and the vertical earthquake accelerates the reinforced concrete column destroyed； The column damage resulted in structure internal force redistribution and final collapse of the （3） entire structure（4）The shear damage and bending damage coexist in the column and the failure type of the lining is mainly the bending damage.
