摘　　要：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。In the paper, 91 samples including sandstone, marble, granite were analyzed for Brazilian split testing by various spacer types. Spacer types can be divided into hard spacer and soft spacer. The tensile strength of soft spacer method is larger than that of hard spacer. The test provides basic data for engineering application of reck tensile strength and the formulation of relevant testing standard.
