地震射线走时层析成像是研究地下深部速度结构的重要地球物理方法之一,本文通过一个地震射线走时层析成像的简单数值计算实例,结合地震射线走时层析成像的基本理论和步骤,使用数值计算,具体讲述了绝对走时层析成像和相对走时层析成像的基本原理和实施流程.与抽象的概念和公式相比,一步一步的实例计算,使读者对地震射线走时层析成像的认识更具体、更直观、更易于理解,作者也希望这个数值实例对初学者能有一定的帮助和指导作用.
Seismic traveltime tomography is one of the most important geophysical methods to study the deep underground velocity structure. Based on a simple numerical example of seismic traveltime tomography, combined with the basic theory and steps of seismic traveltime tomography, Computation, specifically about the absolute travel time tomography and relative travel time tomography of the basic principles and implementation process.Compared with the abstract concepts and formulas, step by step example calculation, so that readers of seismic travel time tomography more understanding Specific, more intuitive, easier to understand, the author also hopes that this numerical example for beginners can have some help and guidance.
