Abstract:

The nonstationary seismic motion for large-scale underground cavern group located in alpine gorge is artificially simulated, based on the frequency analysis of near-site seismic log and bedrock response spectrum obtained by seismic hazard analysis. The trigonometric series superposition, under the control of two predominant frequencies by the Fourier transform of Panzhihua earthquake records, is used to simulate the seismic motion with consideration of depth modification, baseline modification and high frequency wave. The other earthquake log with similar geological background is also used to get the frequency spectrum if the near-site earthquake log is absent. The finished artificial seismic motions, as the numerical simulations show, fit the numerical analysis softwares such as FLAC and ABAQUS well.

Key words: large-scale underground cavern group, nonstationary artificial seismic motion, spectrum, baseline modification, high frequency wave
