摘要
介绍了小区域GPS地壳形变监测网建立、观测和数据处理方法,提出了一种平面直角坐标下位移—应变关系计算模型,得到监测区的位移场、应变场及断层活动方式,进一步得到主应变及方向、最大剪应变、面膨胀等应变参量及应力。
This paper introduces establishment of GPS monitoring network for crustal deformation and observation method and GPS data processing. It puts forward a modeling algorithm of displacement-strain in plane rectangular coordinate system. The displacement fidd and a strain field and a way of faulting were obtained in motion. Strain parameters and stress may be obtained further including main strain and azimuth, maximum shear strain, and dilatation.
