Title: Experimental research on marble rock strength of a hydropower station
Abstract: In this paper,the triaxial compressive tests on natural state and saturated marble are conducted with a variety of confining pressures analysis.The experiment result shows that the strength of natural rock is larger than the strength of saturated rock under the same confining stress.Under the same saturated state,peak strength and residual strength both increase with the confining stress,but the peak strength is not directly related with confining stress value.At last,the best relationship curve and exact expression are obtained by using the least square method.
