Experimental study on the structural failure characteristics and load-bearing mechanism of anchored fractured rock mass
Henan Polytechnic University · State Administration of Work Safety
Abstract
Bolt support is one of the primary techniques for enhancing rock mass stability, and the degree of fracturing in the rock mass significantly influences the strength and failure behavior of the anchored rock mass. To investigate the failure characteristics and load-bearing mechanisms of anchored fractured rock masses, a self-developed three-dimensional physical simulation test system was employed to conduct comparative loading tests on anchored specimens with varying fracturing degrees reinforced with prestressed bolts. The mechanical response of the anchored fractured rock mass was analyzed based on four aspects: stress-strain curves, failure modes, bolt axial forces, and acoustic emission characteristics. The…
