The transformation of the free-field displacements to the underground structure is analyzed in the paper. On the basic of soil strain transfer to structure, defined as STC, and taking subway structure as object, By using the two-dimensional nonlinear dynamic FEM suitable for the larger deformation and seismic time history, the effects of variation of the parameters including the input earthquake motion, the soil property and soil layer as well as the feature of the underground structure on the STC are investigated. The calculated results indicate: (1) The STC decreases with the increasing of input acceleration amplitudes approximately and the relation between can be described as parabola; (2) Generally, The STC in the soft clay is linearly proportional to the modulus of the soil and the STC in the harder clay with the equivalent shear wave velocity larger than 220m/s is the hyperbolic relation with the modulus of the soil; (3) The influence of the soil layer thickness for soil layer with the depth less than 40 meters can be neglected basically; (4) For the structure with the width-to-depth section ratio from 1 to 2, the STC keeps a constant basically; (5) If the buried depth of structure is less than 10 meters, the buried depth of the structure can be ignored basically.
