At the present time,the most of experimental researches on steel fiber reinforced concrete are only under conditions of static or dynamic uniaxial compression,and dynamic triaxial compressive experiment is rare.According to this situation,the triaxial compressive experiment of steel fiber reinforced concrete under conditions of dynamic load was carried out.Based on the data of experiment,the relationship between stress and strain of steel reinforced fiber concrete under dynamic triaxial compression steel fiber concrete is analyzed in this paper,the influences of steel fiber's volume ratio and confining pressure on the dynamic ultimate compressive strength and deformation properties of steel fiber reinforced concrete are discussed,and some useful conclusions are gave out.
