摘要: 综述了近10多年来国内外利用大地测量资料反演研究构造应力应变场的理论成果及最新进展重点讨论了重力场与应力应变场的关系总结了利用大地测量数据反演构造应力应变场的研究内容和应用领域并分析了存在的问题 对利用大地测量资料反演构造应力应变场的研究进行了展望大地测量技术的发展将会继续推动利用大地测量数据反演构造应力应变场理论的完善和应用的深入建议构建弹性粘弹性和弹塑性的利用地面重力数据确定地壳构造应力应变场的解析模型联合多类数据反演时变地壳构造应力应变场进一步加强研究时变地壳应力应变场和地震应力触发机制之间的关系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．
