摘要
本文综合论述了环青藏高原地区(主要指青藏高原东部边缘地区)主要断裂活动性及其内部构造块体运动状况两方面的构造形变场特征,并将其置于青藏高原这个完整的地球动力学环境体系中,在建立青藏高原构造动力学模式的基础上,用离散元法模拟分析了环青藏高原地区上述两方面的构造形变场特征,最后综合上述定性定量分析结果,从理论上阐明环青藏高原构造形变场形成的构造动力学机制。
The authors discuss systematically in this paper the characteristics of tectonic deformation field around Qinghai-Tibet Plateau, i. e.,the mobility of chief active faults and the relative motions among the tectonic blocks.Set in the complete geodynamic environmental system of Qinghai-Tibet plateau the tectonic deformation filed around Qinghai-Tibet plateau is simulated by discrete element method. Finally the dynamic mechanism of formation of the tectonic deformation field around Qinghai-Tibet plateau is elucidated theoritically by synthesizing the quantitative and qualitative analyses.
