Abstract:For the purpose of detailed study of the Xianshuihe fault activity, the disclination-dislocation model is put forward in this paper. This model combines GPS data in the area of 2001-2004 with article swarm optimization to inter-fault sliding and rotation at different segments of the fault zone.Wethen verify the reliability of fault parameters based on forward calculation. Our results show: 1) The Xianshuihe fault zone, which presents left-lateral strike-slip movement on the whole and extrusion on the local scale, gives priority to sliding characteristics; 2) The Xianshuihe fault zone presents more rotation characteristics in the southeast segment than in the northwest segment.
