The seismic response of underground structures in nonlinear foundations was analyzed by using FLAC 3D software, and the effect of relative wavelength on the transverse strain transfer rate of structures is studied. The variation processes of the strain transfer rate can be divided into three distinct phases. In the first stage where the relative wavelength raises from 0.2 to 1.0, the strain transfer rate increases almost linearly with it; while in the second stage where the relative wavelength increases from1.0 to 2.0, the growth trend is slowing down. And the strain transfer rate almost keeps a constant value during the last phase, in which stage the uniform strain field of soil can be used to analyze the strain transfer rate. According to the influence of relative wavelength and relative stiffness on the strain transfer rate, the calculation formula of the strain transfer rate is summarized.
