摘要: 国内已有不少地震队涉足复杂构造的山区工作,甚至冻土山区工作,这种地面与地下的双重复杂性要求地震工程师必须考虑若干有关的特殊问题。实际上,其中一些问题对黄土塬和沙漠地区也有某种共性。山区地震效果如何能为石油勘探界所普遍关心,亟待地震工作者投身探讨,须在试验中加深认识,提高工作水平。文中列出并探讨了四项主要技术问题,即散射波干扰、静校正方法、偏移归位以及与大地的耦合;从实际可行角度,本着尽可能简化与轻便的原则,理出一条方法研究思路,须在实践中验证与改进。

Abstract: As everyone knows,rough terrain and complex subsurface are often co-existent,and a lot of related special problem have to be considered by the seismic engineer.Some of the problems are in fact common to loess plateaus and dune deserts.It is therefore a technology much concerned by petroleum explorationists and so awaiting seismic workers to devote their efforts in the discussions and experiments for knowing and doing better.This paper begins with stating four major technical problems,i.e.,.back scattering,static corrections,migration of data and coupling to the earth,then from a practical point of view in pursuing portability as well as reasonable simplicity, presents how the experiments could be performed.The opinions or proposals included herewith need to be confirmed in the future.
