摘    要:围岩松动圈是地下工程中普遍存在的实际物理力学状态,它对地下工程的稳定性影响很大,围岩松动圈准确地无损检测,可以合理地确定支护参数。比较分析了折射波法、钻井超声波法以及探地雷达法等三种围岩松动圈测试的地球物理方法,指出其适用的基本假设条件,并且应用前人的实例说明三种方法的优点及其局限性,最后指出围岩松动圈检测方法的发展方向。

关 键 词:围岩松动圈  折射波法  钻井超声波法  探地雷达法  无损检测

Abstract:Broken zone of the surrounding rockmass is ubiquitous the physical dynamic state in underground engineering. It effect on the stabilityof under ground engineering. The harmless detection of flexible circle may determine the parameters of timbering. The geophysical methods of harmless detection of broken zone using refraction, drilling ultrasonic and radar are introduced in this paper. Wepoint out what are theirapplicable assumptive conditions. Moreover we use the exampleto illustrate theiradvantage and disadvantageand limitation. Finally we point outtrends of the development of the harmless detection of broken zone.
Keywords:Broken zone of the surrounding rockmass  refraction  drilling ultrasonic  radar  harmless detection
