摘要
目前,钻孔雷达技术在国外已被广泛应用于各领域,但相对于我国来说还是一种新技术。由于钻孔地质雷达可以探测到比地面地质雷达更深的地质目标体,因而可广泛应用于水文地质与工程地质领域,用来探测深部的断层、裂隙及破碎带等不良地质体。本文首先概述了目前国内外钻孔雷达在水文地质与工程地质领域的应用和研究情况;然后通过实例详细分析了该技术在实际工作中的应用效果;最后总结了钻孔雷达技术在水文地质与工程地质方面的应用优势,并指出了钻孔雷达技术现阶段存在的一些问题及其未来在我国的发展方向。
Because borehole radar can penetrate the deeper targets than surface-penetrating radar,it can wildly be used to survey the adverse geological masses such as the deep faults,cracks and fracture zones.Based on the excellent achievements for borehole radar at home and abroad,the progress of borehole radar used in hydrogeology and engineering geology field is summarized and its working theory is briefly introduced.Through the engineering practice,the results of the borehole radar used in engineering geology investigation are analyzed in detail.At last,the application advantages of borehole radar are summarized,and the subsistent problems and the future development of borehole radar are pointed out.
