摘要

电磁波速度或衰减层析成像技术单独用于岩溶勘察存在多解性缺陷，降低了应用的准确性。基于电阻率和相对介电常数直接反映溶洞与周围介质存在的电性差异，以电磁波速度和衰减层析成像理论为基础，提出了电阻率和相对介电常数层析成像理论，并应用于实例工程。通过对其电磁波速度、衰减、相对介电常数、电阻率4参数层析成像结果进行对比分析和钻探验证，证明了基于电磁波的电阻率和相对介电常数层析成像技术是可行的，形成了电磁波速度、衰减、相对介电常数、电阻率多参数层析成像综合分析方法，提高了电磁波层析成像技术探测溶洞及其充填情况的准确性。

Abstract

Applying electromagnetic wave velocity singly for karst survey

there are limilations because of multiple solutions

and so does attenuation tomography technology. And the veracity is reduced. Based on the electric differences between karst cave and ambient medium，which are directly reflected by resistivity and relative dielectric constant

theories of resistivity and relative dielectric constant tomography are put forward

depending on the theories of electromagnetic wave velocity and attenuation tomography. Furthermore

it is applied to project. It is proved that the technology

relying on resistivity of electromagnetic wave and tomography of relative dielectric constant

is doable by analyzing four parameters

such as electromagnetic wave velocity

attenuation

relative dielectric constant and resistivity. A method of multi-parameter tomography compositive analysis is formed. As a result

the veracity of applying tomography by electromagnetic wave for detecting karst cave and it’s filling increases.
