基于GAMIT/GLOBK大陆构造单元稳定性研究

The Research of Stability of Tectonic Units Based on the GAMIT/GLOBK

中国大陆板块内部构造变形复杂,火山、地震等活动频繁,这导致各构造单元运动剧烈.因此研究今中国大地构造格局以及构造单元的相对移动趋势具有重要的意义.利用GAMIT/GLOBK软件对近几年某些构造单元的位移方向和位移量进行分析,提出了一套完整的大陆构造单元稳定性分析的方法和流程,并通过IGS站数据进行了验证,结果表明该方法可行.基于GAMIT/GLOBK的GPS定位方法为大陆构造单元变化分析提供了先进、高效的手段和方法.

The inside tectonic units of China Mainland deformation are complex, volcanic and earthquake activity are frequent, it causes the drastic movement of tectonic plates. So the research of the tectonic pattern of present China and the relative movement of trend tectonic units are of great importance. In this paper, using GAMIT/GLOBK software to analyze displacement direction of the certain tectonic units and displacement in recent years, and propose a complete set of analysis method and processes on stability of continental tectonic units, and verifie by the IGS stations data. Results show that the method is feasible. GPS positioning method based on the GAMIT/GLOBK provides an advanced and efficient means and methods for tectonic units deformation analysis.
