摘要
Based on the fault dislocation model of Yoshimitsu Okada and Steketee and filed scientific investigation, the authors calculate theoretically space variation of the displacement fields. In the simulation, the authors interpret the space variation of the displacement field in the near zone of Yingxiu-Beichuan reverse fault in details which can’t be described by the field scientific investigation and limited data of GPS stations. Comparing with the results of field science investigation on surface rupture zone, the results show that the displacement fields have the same variation trend.
