SPAC法在江汉平原地层结构分层中的应用
Application of SPAC Method on Stratification of Stratigraphic Structure in Jianghan Plain

微动探测可以确定岩土性质差异较大的地质界面。利用微动探测方法，获取S波速度剖面，对潜江市浩口中学地下介质结构分层，并与该场地地震监测井项目的钻孔对比。结果表明，微动探测方法能较好分辨地层结构，对岩土性质差异较大的地层探测效果良好，可为地层分层提供重要依据。
The microtremor survey can be used to evaluate geologic interfaces with large differences in their geotechnical properties. Using the microtremor survey method to obtain the S-wave velocity profile, we then compared the stratigraphic strata at the Haokou middle school in Qianjiang City with the borehole results obtained by the earthquake monitoring project at the site. The results show that this method has the advantages of high resolution of the stratigraphic structure and good exploration of strata with different geotechnical properties, which can provide an important basis for understanding the stratigraphic stratification
