Development of a trench cutting re-mixing deep wall method model test device [PDF]

open access: yes, 2020
The trench cutting re-mixing deep wall (TRD) is a new type of underground waterproof curtain. Mixing uniformity is the key index affecting the efficiency and quality of this method.

Effects of joint geometric configurations on cyclic shear behavior of intermittent joints under constant normal stiffness conditions

open access: yesDeep 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 ...

Probability prediction of true‐triaxial compressive strength of intact rocks based on the improved PSO‐RVM model

open access: yesDeep 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

The Influence of Engineering-Geological Conditions on the Construction of the Radioactive Waste Dump [PDF]

open access: yesActa Montanistica Slovaca, 2007
A secure stability and reliable serviceability of the radioactive dump is a difficult engineering problem. Due to the difficult geological formations determined mainly by a high compressibility, the low shear strength of soils, and the high ground water ...

Numerical investigation of the correlations of hydraulic and elastic characteristics in diverse carbonate rock types

open access: yesDeep 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.

Investigation of gold nanorods as a sensing material in plasmonic sensor for triclopyr butotyl detection [PDF]

open access: yes, 2020
Gold nanorods (GNRs) have a unique optical property of metal nanoparticles (MNPs) due to the localised surface plasmon resonance (LSPR) effect, which depends on the size, shape and dielectric property of the surrounding medium.
