Water decoupling charge blasting excels in rock breaking, relying on its uniform pressure transmission and low energy dissipation. The water coefficients can adjust the contributions of stress wave quasi-static pressure. However, quantitative relationship between two is unclear, it difficult to provide reasonable theoretical support for design blasting. In this study, a model fracturing partitioning established. mechanical mechanism determination method optimal coefficient are obtained....
Geopolymer is a kind of material with better ability high-temperature and corrosion resistance. Poor adhesion could easily lead to problems such as coating cracks, peeling at an early stage, inability work the substrate. The depends on many factors chemical composition raw materials, formulation geopolymer, type substrate, surface roughness etc. higher Si/Al ratio, greater shear strength coating. This because geopolymers synthesized different ratios have phases in geopolymer binder. Each...
Fissure fillings are critical to the hydro-mechanical properties of jointed rock masses in engineering. In this study, triaxial seepage tests were performed on standard cylindrical fissure-filled sandstone. The characteristics stress–strain relationships, absorption and consumption energy, variations deformation resistance, permeability evolution during experimental process, along with crack development observed post-failure computed tomography scan images sandstone specimens analyzed....
The determination of dynamic properties is great scientific significance to the constitutive modeling and parameter large deformation for sand liquefaction. For Fujian standard sand, a new high-precision KTL bidirectional triaxial test system was used carry out liquefaction tests under equal consolidation different amplitude cyclic stresses. characteristics such as stress strain results, pore water pressure model, effective path, stress-strain relationship curve, were studied. main results...
This study investigates the wetting characteristics and kinetic behavior of amphoteric ionic surfactant on microscopic "solid-liquid" interface coal based low-field NMR experiment combined with molecular dynamics simulations, since basic research mechanism seam water injection is not systematic in-depth enough, which restricts further development dust control technology in mines. Firstly, (CAB-35) different degrees metamorphism dynamic spreading range were obtained by experiment, revealing...
The ventilation shaft of Mount Motian tunnel is an inclined with a dip angle 24°21'48". Investigations were conducted to evaluate the feasibility applying single pass lining (SPTL) steel fibre reinforced shotcrete (SFRS) as permanent lining. Concrete mix ratio tests carried out find proper under which optimum strength and degree slump can be achieved. Tests performed on specimens cut from sprayed samples for flexural cleavage tensile shotcrete. Results showed that inclusion largely increased...
In recent years, there has been an increasing amount of literature on pile’s effective length. A number studies have found that the single length could be computed by means different methods which are unsuitable for grouped piles’ computation. order to understand how piles should calculated, a series was performed in this paper. On basis numerical analysis foundation, results indicate existence Taking engineering example as case, both finite element and semi-analytical used analyzing. It is...
The particle feeding system is a prerequisite for the realization of impact drilling technology. Because high density, storage and flow steel are different from those other nonviscous particles. differential equation movement was built with liquid bridge force model discrete element method. dynamic process distribution state particles in high-pressure tank were analyzed. For 1 mm particles, mass rate decreased increase water content. 2 3 content 15% 20% dividing point increasing to...
