... test in this situation; The LSR method cannot be used on the condition that the calibration accuracy is less than 0.1 um. Introduction Granite is a kind of hard and low-porosity rocks. Researchers in all over the world [1–6] processed many studies on damage of the granite one of the typical brittle...

... and utilization. Over the years, a lot of related researches about acoustic emission characteristics and mesoscopic failure mode involving the extension of cracks of rock under high temperature were made at home and abroad. Wu Jin-wen et al. [1],[2] tested the creep acoustic emission rule of granite (ϕ200mm×400...

... simulation were carried out to study the behavior of typical Hong Kong rocks. For the laboratory tests, the deformation properties (expressed by stress-strain curve) and failure process of granite under compression and tension were investigated. In addition, the evolution of dilatancy and time-dependent...

... Abstract The hydromechanical behavior of deep intact Beishan granite is investigated with MTS815 rock mechanics test system. With the help of 3D acoustic monitoring system, a special attention is paid on the damage evolution process and its impact on the permeability of rock sample during...
