Triaxial Load Test of Steel Fiber Shotcrete for Mine Gateway Support
Abstract：In order to discover the mechanics performances of the steel fiber concrete under the triaxial load effect which often applied to the mine roadway support.with the rock triaxial testing machine,the triaxial test under the different conditions was conducted on the steel fiber concrete specimens.The statistics and analysis of the test data showed that the optimum volume rate of the steel fiber concrete would be about 1.5%-2.0%.Meanwhile,the paper summarized the relationship formula between the ultimate compressive strength and the surrounding pressure of the steel fiber concrete under the triaxial load effect.The higher surrounding pressure,the higher ultimate compressive strength of the steel fiber concrete would be and the plasticity would be better.
