Abstract Engineering rock containing flaws or defects under a large water source is frequently subject to the couple influence of constant crack pressure and geostress. To investigate fracture behavior precracked hydromechanical coupling with pressure, compression tests were conducted on red sandstone specimens single different angles using device realize during loading, failure process was monitored by acoustic emission (AE) technique. The results show that presence has significant...
To investigate the fracture mechanism of rock–concrete (R–C) systems with an interface crack, Brazilian splitting tests were conducted, a focus on understanding influence crack angle failure patterns, energy evolution, and RA/AF characteristics. The study addresses critical issue in structures, particularly how propagation differs varying angles, which has direct implications for structural integrity. experimental results show that paths R–C disc specimens are highly dependent angle. For...
To achieve the actual situation of water pressure stabilization during underground and tunnel inrush disasters, team independently developed a stable test system conducted fracture failure tests on fissured rock masses under coupling effect 1MPa stress without pressure. Combined with data collected by acoustic emission instruments, mechanical characteristics failure, crack propagation mechanism, response mechanism hydraulic were studied. The results showed that throughout entire experimental...
A new model is established to analyze mining stope stability, using variable weight theory calculate the index for each factor in different stopes and unascertained measure evaluation technique predict risk grade of stability. In this model, an system by virtue 7 most important factors established, including rock saturated uniaxial compressive strength, quality designation, joint fissure, span, condition pillar, groundwater seepage volume, rate supporting pit roof. And divided into 5 grades...
Considering the heterogeneity of rock, study specimens with multi-fractures under uniaxial compression has been made by RFPA<sup>2D</sup> software. It was aimed to explore influence different angle and density fractures on failure mechanisms which belong rock-like materials multi-fractures. Numerical analysis is consistent experimental results. The shows that overall process a gradual-sudden change, can be divided into 3 phases: elastic deformation stage, crack initiation stable expansion...
To accurately determine the stress characteristics of underground rock masses subjected to hydraulic pressure and reveal crack-initiation, crack-propagation, macromechanical fractured under long-term pressure, a loading system that can deliver continuous stable was developed. The is composed device supplies flowmeter, gauge, acoustic emission instrument, device, control system. main innovation test lies in stabilization which distinguishes new from traditional devices provides several...
The photocatalysis technology has become an important means to control environmental pollutions especially water pollution. A new ZnO/sepiolite composite was prepared using the sol–gel method by taking nontoxicity, high catalytic activity, stability, and strong antioxidant capacity of ZnO large pore volume specific surface area, adsorption capacity, light weight, chemical stability sepiolite prepare improved photocatalytic materials. microrepresentation contrast analysis structures...
