Pile foundation analysis of ground motion transfer law

Based on shaking table model test, each response of the pipe models is obtained by inputting different types, amplitudes, frequencies of seismic waves and white noise excitation. The transfer function of the measuring point related to the vibration table, natural frequency of soil and pile, power spectrum and other parameters are obtained by Matlab programming model. By applicating SeismoSignal the propagation of seismic waves in the soil was gotten. Reveal the regulation of the propagation of the seismic waves in the pile-soil system. Investigate dynamic characteristics and dynamic response of the pile and soil in the earthquake and the transfer laws of the seismic wave energy. Provide a useful reference for the pile foundation seismic design.
