地质雷达特征图像与典型地质现象的对应关系

地质雷达是浅层地质勘探的有效方法,其对断层破碎带、裂隙带、富水带、岩溶洞穴等不良地质灾害有明显的异常反映。地质雷达测量方式、测线布置及系统参数的选择,可根据测量环境以及探测目标体的大致走向、规模、物性等情况综合分析,做出合理选择。通过用地质雷达对多个工区进行工程勘查,从地质雷达图像的波形、频率、振幅、相位及电磁波能量吸收情况(或自动增益梯度)等细节特征的变化规律出发,建立了典型地质现象与地质雷达特征图像的对应关系,可以作为地质雷达图像解释的重要判据。

Correspondence between geological characteristics of radar images and typical geological phenomenon

Geology radar,which is used widely in the geological prospecting investigation,is a powerful tool using in shallow geological survey to detct faulted zone,fractured zone,water abundant zone and karst caves.In this pa-per,the actual radar geological prospecting works on the basis of applications,the establishment of the geological characteristics of the radar images of several common with the typical geological phenomenon counterparts,for future geological radar image analysis and the basis of identification,conducive to the use of ground penetrating radar images to discriminate analysis and geological phenomena accumulation of geological interpretation of the radar images experience.
