该文对砂岩、大理岩、花岗岩三种岩石共 91件试样采用不同的垫条方式进行岩石劈裂试验。分析认为可归为硬垫条和软垫条两类 ,且软垫条方式所测岩石抗拉强度大于硬垫条方式。试验为岩石抗拉强度的工程应用及制订相应的试验规范提供基础研究
In this paper, a total of 91 samples of sandstone, marble and granite were used to conduct the rock splitting test with different padding methods. Analysis that can be classified as hard and soft padding two types, and the method of testing the tensile strength of the rock is greater than the hard pad way. Tests provide basic research for engineering applications of rock tensile strength and the development of appropriate test specifications
