摘要(Abstract):
为了更好地测量岩石的压缩系数,分析了传统的测量岩石系数的体积法存在的缺陷。体积法因存在表皮效应,而使得测量结果缺少基本的合理性。在此基础上,根据岩石压缩系数的理论计算公式,提出了测量岩石压缩系数的新方法"弹性模量法"。新方法彻底消除了表皮效应的影响,而使得测试结果趋于合理。
In order to accurately measure rock compressibility,the defects which generate from former volumetric method are analyzed.Because of skin effect,the results are absence of basically rationality.Thus,based on their theoretical computation formula,a new method named by elastic modeling quantity is provided,which absolutely eliminates effects of skin effect and makes the measurable results reasonable.
