摘要
回顾了GPS观测技术应用于地壳运动与形变中的相关理论与方法,重点介绍了水平应变的计算方法与描述地壳运动与形变场的各种数学物理方法,讨论了提取地壳运动与形变信息过程中存在的问题。
High precision GPS network,using to monitoring the crustal movement and deformation of large,middle and small scales,are established in Chinese mainland and its surrounding areas,because the precision of spatial geodetic technology,such as GPS,is improving in the past nearly two decades.The relevant theory and methods for studying the crustal movement and deformation with application of GPS technology are reviewed.The methods of calculating horizontal strain are introduced.The math-physical methods of describing crustal deformation field are introduced with special attention. The progress and existing problems of the study on Extraction the sign of crustal movement and deformation from space geodetic measurements are discussed.
