Deep Underground Science and Engineering, EarlyView.The permeability variation of rocks during complete stress–strain processes was investigated. A mathematical model describing the influence of rock damage on permeability was constructed. The permeability–stress relationship between soft rock and hard rock was proposed.

Comparisons of soil suction induced by evapotranspiration and transpiration of S. heptaphylla [PDF]
, 2015 For a given evapotranspiration (ETr), both soil evaporation and plant transpiration (Tr) would induce soil suction. However, the relative contribution of these two processes to the amount of suction induced is not clear. The objective of this study is to

Strain‐based modeling and analysis for rock blasting and geomechanics applications
Deep Underground Science and Engineering, EarlyView.This paper introduces a novel strain‐based modeling approach for blasting and geomechanical applications, using measurable variables like particle velocity, strain, and displacement. By bypassing complex constitutive relations, strain‐based models capture critical blasting trends and full‐blast design parameters with minimal calibration.

Deep Underground Science and Engineering, EarlyView.The present manuscript explored the effects of joint configurations on the cyclic shear behavior of intermittent joints for the first time. The cyclic shear response, shear strength degradation, dilation characteristics evolution, frictional property, fractal dimension, and dissipative energy were further analyzed during shear cycles, which is crucial ...

Experimental analysis of 3D cracking in drying soils using ground-penetrating radar [PDF]
, 2017 This paper describes the capabilities of a novel technique to investigate crack formation and propagation in drying soils. The technique is a relatively simple, non-destructive indirect technique using a ground-penetrating-radar (GPR) system to detect ...

Deep Underground Science and Engineering, EarlyView.In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type

Deep Underground Science and Engineering, EarlyView.We use the linear Boolean model and the discrete Fourier transformation approach to generate various carbonate rocks. The lattice Boltzmann method and the finite element method are applied to calculate permeability and elastic wave velocity, respectively.
