Study on mechanical properties of sandstone damaged by blasting load under triaxial cyclic loading and unloading
Published 2025-01-01“…An increase in the confining pressure enhanced the deformation and failure resistance characteristics of the specimens. (4) Compared with those under conventional triaxial loading, specimens under cyclic loading and unloading failed faster after reaching the ultimate volumetric strain, and specimens damaged by blasting were more likely to fail. During deep coal mining, the bearing capacity and deformation resistance of rock masses damaged by blasting after repeated disturbance loads were greatly reduced. …”
