Abstract：The analysis of muli-point ground motion characteristics with space distance ,frequency is performed.Following a brief review of pertinent results from the second-order theory of random fields ,a new mathematical model is proposed ,as an enhancement on the model of Harichandran-Vanmarcke ,this article take the 2D spatial factor into account .The acclerograms recorded by SMART 1 seismograph array in Lotung Taiwan are used to determine the parameters of the correlation model , Finally the preliminary comparison is made with the Hao model ,it is shown that the proposed model has a excellent performance.
