韧性剪切带中刚体运动学模拟技术最新研究进展

Latest development of simulation technique of rigid body kinematics in ductile shear zones

韧性剪切带是构造地质学研究的重要内容。传统研究韧性剪切带主要是野外露头解析和室内显微构造研究来综合判断剪切带的属性。近些年来,许多国内外学者对于剪切带中刚体(砾石、颗粒等)的研究,特别是使用模拟软件(如:Ansys、Matlab、Mathcad)试图恢复刚体的运动学轨迹,拓宽了学者们对于韧性剪切带中赋存刚体的研究思路。目前,对于刚体的模拟研究介绍甚少。基于此,本文对韧性剪切带中如何定量研究刚体的理论进行详细的介绍,并利用Mathcad编写程序恢复了刚体在给定条件下的运动学轨迹。

Ductile shear zone is an important subject in the research of tectonics.The traditional study of ductile shear zone focuses on discrimination of property of shear zone through analysis of outcrops in the field and indoor study of microstructure.In recent years scholars from China and abroad tended to study the rigid bodies in shear zone（gravel and grain）and they attempted to recover the kinematic trajectory of rigid bodies by using simulation software（Ansys,Matlab,Mathcad）while it also broadened the ideas of research on rigid bodies occurred in ductile shear zone.In light of the scarcity of introduction to simulation study on rigid body,this paper elaborated on theories of quantitative study on rigid body in ductile shear zone and recovered kinematic trajectory of rigid bodies under certain conditions by using Mathcad.
