摘要
文章以层状地层模型为例,得到溶洞模型的电磁波CT正演模拟数据,采用水平测线值的网格初始模型进行迭代反演,将反演成像结果与原始模型进行对比分析,对比数据标准化后的异常显示情况.结果表明,min/2-max标准化后异常区边界清晰,与模型吻合较好.将min/2-max标准化应用于项目中,无论是小溶洞还是大溶洞都能取得较好的探测效果,提高了异常解译的准确度.
Abstract
In this paper,taking the layered stratum model as an example,the electromagnetic wave CT forward simulation data of the karst cave model are obtained.The initial grid model of the horizontal line value is used for iterative inversion.The inversion imaging results are compared with the original model,and the abnormal display after data standardization is compared.The results show that the boundary of the anomaly area is clear after min/2-max standardization,which is in good agreement with the model.The application of min/2-max standardization in the project can achieve better detection results in both small karst caves and large karst caves,and improve the accuracy of anomaly interpretation.
