Abstract:
This paper reviews the progress and the theoretical achievements in stress-strain calculation using geodetic measurements over the past ten years and profiles domestic and international research with a discussion about the relationshi p between the gravit y and stress-strain fields.Studies and applications of stress-strain inversion using geodetic data are summarizedand the outstanding problems are anal yzed.The development of geodesy technolo gy will continue pushing for the perfection of the inversion theor y of the crustal stress-strain field using geodetic data.We suggest that the anal yticall yelasticvisco elastic and elasto plastic crust models relating ground gravit y to the stress-strain field can be completel y articulated and applied.We also conclude that studies concerning the relationshi pbetween spatio-temporaltectonic stress-strain fields and seismic stress tri ggering in the crustas wellas joint inversion for spatio-temporal tectonic stress-strain fields with multi-source datashould be de-veloped.
