摘要
对浅层地震勘探折射CT反演法的原理进行了简要介绍,并指出其常规反射波法的不同之处,然后以榆林至绥德高速公路某隧道为例,采用CT反演法对数据进行综合分析处理,得到的基岩面实际钻孔探测结果基本一致,提高了工程地质勘察的时效性准确性,为以后的勘察工作提供了一种新的手段。
This paper has recommended the principle of CT inversion method in the first,then the difference on the CT inversion and reflectometry is commented,at the last,taking the Yulin-Suide highway as the example,adopts CT inversion method to undertake the comprehensive analyzing treatment of the date,concludes the bedrock is basically consistent with the factual drilling detection results,and it can improve the timeliness and accuracy of the engineering geological observation,and a new method for geologic survey is supplied.
