| 摘 要： | 电磁波CT法以其高分辨率、高精度、强抗干扰能力等优势在在工程地质勘察中得到广泛应用。以贵州某工程勘查项目为例，利用井间电磁波CT方法进行大规模、高密度的数据采集，对采集的数据进行单孔反演、剖面拼接，并利用三维成像技术建立了吸收系数模型。综合分析结果表明，利用拼接剖面及三维模型可以识别单孔剖面无法发现的破碎带、地下暗河异常，清晰地展示出基岩面及溶蚀区域的空间形态，可为后续岩溶治理工作提供重要的基础资料。

| Abstract: | Electromagnetic wave CT method has been widely used in engineering geological exploration due to its advantages of high resolution,high precision and strong anti-interference ability.Taking an engineering exploration project in Guizhou as an example,the cross well electromagnetic wave CT method was used to conduct large-scale and high-density data acquisition,perform single hole inversion and section splicing for the acquired data,and establish the absorption coefficient model using 3D imaging technology.The comprehensive analysis results showed that the splicing profile and 3D model could be used to identify the fracture zone and underground river anomaly that could not be found in the single hole profile,clearly show the spatial morphology of the bedrock surface and the dissolution area,and provide important basic data for the subsequent karst treatment work. |
