摘要
为了更好地解决重力勘探中的正演、反演问题,提高重力勘探资料的解释精度,在MatlabGUI程序开发环境下对地球物理多个球体重力异常正演问题进行了研究与程序编写,重点研究了一个均匀球体、两个及两个以上均匀球体模型的正演模拟,使一些较复杂的重力问题能够通过多球体模型近似模拟得以解决。该正演模拟程序界面简洁,操作方便,可交互输入球体模型深度、密度、半径等参数,模拟结果可进行三维、二维等多方式显示,三维曲面可任意调整观测视角,二维曲线可任意选择测线位置进行显示。本程序的模拟结果可以为复杂球体重力勘探资料解释与反演提供参考,也是球体重力问题正演研究的有效手段。
In order to solve the problems of forward and inverse gravity method, and for im- proving the precision of gravity data interpretation, this paper based on the MatlabGUI de- velopment and environment discussed gravity anomaly forward modeling of multiple spheres and how to write the processing MatlabGUI codes. The main researching results focused on the forward modeling problems of one homogeneous sphere, two homogeneous spheres and several homogeneous spheres. It makes some of the more complex gravity problems be solved by multi-sphere gravity simulating approximately. The forward simulation program has a simple interface, and its operation is convenient. The sphere model depth, media density, sphere radius and other parameters can be input interactively. The simulation results can be displayed in the three-dimensional space or in a curve. The 3D figures can be observed in any direction by adjusting the showing angle. A line gravity curve can be dis- played conveniently by inputting the line parameters. The procedure simulation results can give us some guides or arouse us ideas for interpreting complex sphere gravity data and doing gravity inversion, The MatlabGUI gravity modellings are also wonderful tools for researching sphere gravity forward problems.
