采用GPS观测值进行三维形变分析的构想
ANALYZING 3-DIMENSIONAL CRUSTAL DEFORMATION WITH GPS OBSERVATION DATA
【摘要】 在已知地表度量张量的基础上,给出了根据测站的GPS复测值计算地表形变张量、主方向、线应变、面应变、高斯曲率与平均曲率的有关公式,并着重对地表的内蕴与外蕴形变概念作了阐述,最后指出利用地表内蕴与外蕴形变量能较好地描述地表的三维形变。
【Abstract】 On the basis of metric tensor of known crust surface,the formula of crustral deformation tensor,principal direction, linear strain, area strain, Gaussian and mean curture on crust surface calculated with GPS observation data are given. The intrinsic and extrinsic deformation are explained.We think that the intrinsic and extrinsic deformation can describe appropriately three dimensional deformation on crust surface.
