英文摘要	Experimental studies on a granite under dynamic compression are conducted at strain rates from 10(-4) to 10(0) s(-1) and confining pressures from 0 to 170 MPa. It is reported that the rock strength increase with increasing strain rates. Under dynamic triaxial compression, the rising rates of rock strength with increment of strain rate have a tendency to decrease with increasing confining pressures. As that of under static loads, the rock strength increase with increasing confining pressures at different strain rates. The rising rates are almost identical under 4 different strain rates studied. It is also observed that the results of measured Young's moduli and Poisson's ratio are scatter and have no clear tendency changing with increasing strain rates and confining pressures.
