Abstract

I used Why-3000 compression servo testing device to do experiments about rock specimens fixed on different angle inclinations. This study systematically analyzed tensile mechanical property of layered rocks with different anchoring configurations at varied dip angle, experimental results show, under unanchored condition, the stress-radial straing curves of specimens exhibited monotonically decreasing trends in all dip angle (0-90) and both tensile strength and strain reached minimum value at 90°dip angle. Anchored and pre-strengthened samples had far greater tensile strength and radial strain than unanchored samples, and with much lower rates of strain increase. To show that rock bolts accomplish complete improvement of bearing capacity by controlling rock mass deformation and altering stress distribution. Watching the same condition of stratigraphic dip angle, preload stress. The tensile strength and radial strain level of the zero degree-anchoringangle specimen is much higher than the 15 degree-anchoring-specimen: It implies that good anchorage angles could take charge of rock mass bearing ability evolution processes because of better stress transition ways and more deformation limitation results.
