摘要
考虑剪切波和超声波测试技术分别能在划分场地类型和判定岩体完整性中应用,因此,本文着重介绍了钻孔声波测试与剪切波测试技术方法,利用相应的测试仪器获得纵波波速值以此来判断岩体状态,配合钻探判定岩体完整性、划分岩体单元以及探测岩体中钻探未发现的溶蚀洞隙、软弱夹层、岩体较破碎带等;利用岩土体的纵横波波速度划分场区内岩土类型,并得到了较好的测试效果。
Considering shear wave and ultrasonic wave can be applied in dividing site type and determining rock mass integrity,therefore,this paper focuses on the methods of drilling acoustic wave testing and shear wave testing,longitudinal wave velocity values obtained using corresponding test instruments,use this to judge the state of the rock mass,Cooperate with drilling to determine the integrity of the rock mass,divide the rock mass unit,and detect the dissolved gaps,weak interlayers,rock masses,and other fracture zones that are not found in the rock mass. The geotechnical types in the field are divided by the longitudinal and transverse wave velocity of the rock and soil,and good test results are obtained.
