福建省地壳形变观测网络建设 总被引:6,自引:5,他引:1
介绍了福建省地壳形变观测网络的建设。福建省地壳形变观测网络,以GPS观测技术为主,结合精密水准、精密重力和流动地磁测量,将3者重合到GPS观测基准站上获取观测信息,初步构成一个时空相结合,点线面与长中短兼顾的高精度、高时空分辨率的地壳形变观测网络。该网络可动态监测福建省东南沿海地区地壳运动变化,为地震预测预报提供背景信息,将取得显著的社会效益和经济效益。 相似文献

采用GPS观测值进行三维形变分析的构想 总被引:2,自引:1,他引:1
在已知地表度量张量的基础上,给出了根据测站的GPS复测值计算地表形变张量、主方向、线应变、面应变、高斯曲率与平均曲率的有关公式,并着重对地表的内蕴与外蕴形变概念作了阐述,最后指出利用地表内蕴与外蕴形变量能较好地描述地表的三维形变。 相似文献

Crustal movement and deformation in Taiwan and its coastal area 总被引:1,自引:0,他引:1
Introduction Both Taiwan Island and Chinese mainland belong to Eurasian plate in geological structure. And the nearest distance between Taiwan Island and Fujian Province, which is located on the opposite coast, is only 130 km. Although there are high-precision GPS networks in both Taiwan and Fujian Province, joint GPS measurement cannot be made directly because of the inconvenient contact due to the strait between them. However, the GPS networks arranged on b… 相似文献
