摘要
通过对复杂地质地表条件的分析研究,总结了近年来在这方面地震波场数值模拟的新方法。复杂地表的类型很多,对地震资料的影响程度不同,要想完全描述近地表的影响因素是不可能的。文中所介绍的模拟方法在处理这些问题上都是各有侧重、各有优势,目的是寻找合适的方法解决适合的问题。
As a tool for understanding the regulation if wave propagation in complex media and examining the effects of different kinds of methods,seismic numerical modeling plays an important role in modern geophysical prospecting.This paper briefly introduced several modeling methods including surface topography in recent years.Our aim is to find the suitable method to solve the adapted questions.
