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。 Currently, borehole radar technology has been widely used in various fields in foreign countries, but it is still a new technology relative to our country. Because borehole geological radar can detect deeper geological objects than ground geological radars, it can be widely used in hydrogeology and engineering geology to detect deep geological faults such as faults, fractures and broken belts. This paper first outlines the current domestic and international drilling radar in the field of hydrogeology and engineering geology of the application and research situation; and then an example of a detailed analysis of the technology in practical application of the effect; finally summarized the drilling radar technology in hydrogeology and Engineering geology, and pointed out some problems existing in drilling radar technology at present and the future development direction of our country.
