围岩松动圈常用测试方法分析与比较
|
摘要
为便于在不同工程背景下对现有多种松动圈测试方法进行选择应用,对获得围岩松动圈范围的理论方法和多种物理测试方法进行了分析介绍,并对各物理测试方法的适用特点进行了比较研究。结果表明:声波法技术相对成熟,但对测试岩体岩性要求较高;多点位移计法测量数据量大,测试精度不高;地震波法与地质雷达法可实现无损检测,但成本较高,适用于精度要求高的工程;钻孔摄像方法直观、精度高,但存在操作复杂、成本高以及不适用于破碎程度高的岩体等缺点。
In order favorable to select and apply available several loose zone measuring and test methods under the different engineering background,an analysis and introduction were conducted on the theoretical method of the loose zone scale in the surrounding rock and the several physical measuring and test methods.A comparison study was conducted on the applied features of each physical measuring and test methods.The results showed that the acoustic method technology was relative mature and would have high requirements of the rock mass lithology measured and tested.The multi-point displacement measuring method would have large quantity measured data and the measuring accuracy would not be high.The seismic wave method and the geologic radar method could have a nondestructive testing,but the cost would be high and the both two methods could be applied to the project with a high accuracy requirement.The borehole camera shooting method would be direct and have high accuracy,but the operation would be complicated and high cost and the method could not be suitable to the highly broken rock mass and other disadvantage.
