多分量地震波交互式速度计算方法的实现

Implementation of Interactive Velocity Computation Method for Multi-component Seismic Wave

针对地震波多分量进行速度分析的技术进行讨论,引入选择性相关法理论,利用精确速度时差方程,结合计算机图形技术,充分利用C++提供的友好界面和Fortran语言在算法方面的优势,自主研发出一套针对金属矿的地震波多分量速度分析软件,实现了速度分析的算法优化和交互性,在一定程度上提高了速度分析的精度,同时,该软件可以方便地移植到其它的大型软件中。

This paper mainly discussed the technique of multi‐component seismic wave velocity analysis and programed a set of software for interactive velocity analysis of seismic wave in mining exploration.Velocity analysis and moveout equation were used together with computer graphics technque on the basis of selected‐correlation method. The accuracy of velocity analysis was improved someway by combining graphic user interface （GUI） provided by VC＋ ＋ and strong algorithmic function provided by Fortran.The software is an open module and can be planted in other software easily.
