Title: Strength Characteristics and Application of Rock Triaxial Compression Experiment
Abstract: In this paper,we discuss the characteristics and application of rock triaxial strength test with the laboratorial examples.The experimental results are shown as follows.①The rock triaxial compression and shearing strengths are shown increment with the confining pressure(depth).Under the low confining pressure,the strengths increase linearly.But when the confining pressure is over the limit,the strengths increase nonlinearly with the accretion rate gradually going down.Under the higher confining pressure,the shearing strength and the differential stress between the compression strength and confining pressure tend to be the constant.②The rock uniaxial strength is the minimum in the all.So the triaxial strength should be applied in the engineering in order to reduce the cost and avoid wasting.③ In all of present rock mechanics experimental methods,the cohesion(C) and angle of internal friction(Φ) from the triaxial experiment is relatively best precise.④The data from rock triaxial test are benefit to the study of the domain correlative to the geology.
