摘要
介绍钻孔弹模计法与声波法的原理和方法,并将该法运用到现场,得到断层破碎带及其影响带岩体的变形特性参数,并拟合得到波速值VP与弹模值E的对应关系。现场结果表明,该法是对破碎岩体测试的一种较好方法。
A method of borehole elastic modulus gauge and a method of acoustic wave are described in this paper, The parameters of rock mass deformation in the fault cracked zones and their incidence are obtained in-situ testing, and get the corresponding relationship between the elasticity modulus E and wave velocity VP through fitting. The in-situ application shows that the method is a better one for testing cracked rock mass.
