| 摘 要： | 海原断裂带和中卫-同心断裂带是青藏高原东北隅二条主要断裂带。通过区域地质、地貌分析和二条断裂带的结构、活动历史的对比研究,建立了该区走滑和挤压活动的应变分配模型。通过对主要断裂带破裂分段的研究,确定了该区的强震破裂单元。应变分配和破裂分段是建立地震构造模型的二个方面。

| Abstract: | The Haiyuan fault zone and the Zhongwei-Tongxin fault zone are main faults in the northeastern corner of the Tibet Plateau. Based on analysis of geology and geomorphology of the region and study on structure and revolution of the two faults, a strain partition model is built to adjust the strike slipping and compressional deformation of the area. Through rupture segmentation study along main faults, rupture units of large earthquakes are also identified in the region. The seismic tectonic model of the region consists of strain partitioning and fault segmentation. |
