重力场深部结构与动力学特征分析

目前重力场结构分析多关注重力场表层,关于重力场深部结构的分析较少,所反映出的地球地质、板块运行等地理信息结论也比较少,为此提出重力场场深部结构与动力学特征分析.计算重力场局部梯度,确定重力场中心和边缘位置,得到重力场场源边界参数,采用反演计算得出重力场深度参数,采用Ueosoft软件的Euler3D模块形成重力场深部结...

Analysis of the Deep Structure and Dynamic Characteristics of the Gravitational Field

At present,analyses of the gravitational field mostly focus on its surface and analyses of its deep structure are fewer.Due to the fact that such geographic informational conclusions as the geology of the earth and the plate movement are rare,this paper proposes the analysis of the deep structure and dynamic characteristics of the gravitational field.The local gradient of the gravitational field can be calculated to determine its center and edge position and obtain the boundary parameters of the gravitational field source.The inversion calculation can be used to obtain its depth parameters and its deep structure chart can be formed by means of the Euler 3D module of the Ueosoft software.Based on the analytical results of its deep structure,the geoid anomaly can be calculated.The inversion can be implemented according to the abnormal results to infer the crustal thickness,changes in crustal tectonic activities and its dynamic characteristics.
