摘要
分析和讨论了位错理论模型的发展历史和应用领域 ,采用走滑和倾滑位错理论模型对青藏高原东北缘的多组断层活动产生的三维形变场进行了数值模拟研究 ,并将数值模拟结果与该地区 1999～ 2 0 0 1年间的GPS观测结果进行了对比分析。得出了甘青块体顺时针转动等一些较重要的结论和认识。
The historic process of dislocation model applied in geodetic field is analyzed and discussed.The three dimensional deformation is calculated by a multi fault model which combining strike slip faults with dip slip faults in northeastern margin of Tibetan plateau. The displacements derived by dislocation model are compared with those observed by Global Positioning System (GPS) during 1999 2001,and some important conclusions have been drawn.
