Experimental study on mechanical properties and failure modes of low-strength rock samples containing different fissures under uniaxial compression

•Specimen material belong to low-strength rock masses.•The influence of fissures on low-strength rock mass is distinguished from that of high-strength rock masses.•The failure of ductile flow deformation occurs in the post-peak failure stage.•UCS, axial peak strain and elastic modulus are most sensi...
