Mechanical properties and cementing characteristics of single strand wire rope used as material of cable bolting for supporting ground around underground openings were investigated. Results of tension tests showed that Young's modulus of the wire rope was approximately equal to that of steel rod and that lateral deformation of the rope was about 30% larger than that of steel rod. Results of pull out test of the wire rope buried in cement mortar showed that tensile force in the rope concentrates in the neighborhood of surface of surface of the mortar, and decreases exponentially torwards inside. Pull out load per unit buried length of the wire rope increased with the buried length. From the results of pull out tests, minimum buried length which brings tension break of the rope seems to be a little larger than one meter. The single strand wire rope used in this experiment seems to be about the same as the ordinary deformed steel rod for rock bolting in its axial rigidity or cementing characteristics. Cable bolting ground support seems to be effective for stabilizing large loosened ground around underground openings.
