走滑断层震间形变GPS观测站点布设的合理性分析

Abstract

Abstract: A reasonable GPS station layout for a single fault can accurately reflect the fault deformation state. The effective distance of far field and spacing of the near field are the important factors that affect observation result. The far-field effective distance should be 6.31 times the locking depth of the fault. The near-field interval is approximated by the segmented line, and the deformation area is divided according to the deformation curve, which is the relation between “near-field and transition zone” and the depth of fault locking. As an example, we analyzed the possible impact of the current layout of the eastern boundary of the Sichuan-Yunnan block on the possible results. The conclusion can provide a theoretical reference for future GPS station deployment.

Key words: GPS station layout, Crustal deformation, Locking depth, Segmented polyline
