【摘要】 用轴向拉伸法和劈裂法进行系统的岩石抗拉强度试验，结果表明劈裂法的误差很大，在工程应用中应采用轴向拉伸法，并为此设计了万向接夹具，解决了轴向拉伸试验中试件轴线的对中问题。更多还原

【Abstract】 Based on the systematic rock tensile strength test by the axial tension method and splitting method,the test results have shown that the error of splitting.method is larger than axial tension method,therefor,the axial tension method should be used in the engineering application,for this reason,the universal connecting holder which is used for the centring of test piece axis is designed.更多还原
