N2 - Since the variances of earthquake waves vary with time, they are not traditional stationary series. Analyzing the earthquake waves by the traditional stationary series method must bring large error. It is found that correlation coefficients of most earthquake waves don't vary with time and are just the functions of time interval. Hence they are correlation coefficient stationary series. The correlation coefficient stationary series analysis and simulation method for earthquake ground motion is established in this paper. The test method for the correlation coefficient stationarity of a earthquake wave is presented, and the estimation method of the parameters of the correlation coefficient ARMA(p,q), abbreviated as CCARMA(p,q), model is given. Based on these analysis results, the artificial earthquake waves can be simulated by the CCARMA(p,q) model. Since the correlation coefficient stationary series describes the essential characteristics of earthquake waves, the presented method can accurately construct the artificial earthquake wave series, which has the same statistical behavior as the actual series.
