给出了青藏高原结构变形的动力学模型及其数值模拟 .模型采用了热传导、弹塑性和大变形的理论 ,利用数值方法给出了从距今 70Ma(百万年 )到现今各个历史阶段的温度场、位移场、应力场以及开裂和滑动等情况 ,得到了青藏高原陆壳的缩短、增厚和隆升之间的定量关系 ,为实现青藏高原动力学的定量研究进行了有益的尝试
The dynamic model and numerical simulation of the structural deformation of the Qinghai-Tibet Plateau are given. The model adopts the theory of heat conduction, elasto-plasticity and large deformation. The numerical method is used to derive the dynamic model of structural deformation from 70 Ma (millions of years) to various historical stages Temperature field, displacement field, stress field, dehiscence and sliding, the quantitative relationship between the shortening, thickening and uplifting of the continental crust in the Qinghai-Tibet Plateau has been obtained, and a useful attempt has been made for the quantitative study on the dynamics of the Tibetan Plateau
