摘要
为了分析汶川地震后的龙泉局部地区地壳形变,本文使用GAMIT/GLOBK软件,以周边三个IGS跟踪站的ITRF2005框架坐标为起算坐标,对龙泉的三个测站进行了基线处理和平差计算。结果表明,汶川地震后龙泉三个测站平均位移向西10厘米、向北7厘米,高程升降约2厘米。
In order to analyze the crustal deformation of Longquan local area after the Wenchuan earthquake based on the ITRF2005 frame coordinates of the three IGS stations near Sichuan,this paper processes the baselines and adjusts the observations of the three stations in Longquan with GAMIT/GLOBK software.The result indicates that the average displacement of the three stations is 10 centimeters westward,7 centimeters northward and about ±2 centimeters in height direction.
