Experimental Study on the Strength Variation of Unsaturated Cohesive Soil in Red Bed with Water Content

Chemical Engineering Transactions, 2018
The shear strength parameter of rock and soil is the basis of engineering design. As the rock-soil environment is ever-changing, geotechnical parameters that are obtained at a certain point of time can represent no other than the geotechnical condition ...

Analytical stress solution framework for lined compressed air energy storage chambers and its application to safe burial depth determination and supporting effectiveness evaluation

Deep Underground Science and Engineering, EarlyView.
An analytical framework delivers a closed‐form stress solution for lined compressed air energy storage chambers, enabling the determination of the minimum safe burial depth. The solution quantitatively evaluates lining support effectiveness, offering a reliable tool for chamber design and optimization.

Advancing mine pillar design: Evaluating traditional methods and integrating AI for enhanced stability of pillars in the Great Dyke, Zimbabwe

Deep Underground Science and Engineering, EarlyView.
B1 is bord width 1, B2 is bord width 2, L is the pillar length, W is the pillar width, red color and letter A represent the pillars, and white color and number 1 represent excavated areas. Pstress is the average pillar stress; σv is the vertical component of the virgin stress, MPa; and e is the areal extraction ratio. e = B o B o + B P ${\rm{e}}=\frac{{

Shear Strength of Compacted Soil under Infiltration Condition

Journal of Geotechnical and Geoenvironmental Engineering, 2004
Landslides in residual soil slopes are commonly induced by rainfall infiltration. These residual soils are typically in an unsaturated state with negative pore-water pressures or matric suctions since the groundwater tables in steep slopes are often deep.

Mechanistic insights across curing regimes for enzymatic and biopolymer‐optimized reinforcement in rock masses

Deep Underground Science and Engineering, EarlyView.
This study examines the effects of curing temperature on the mechanical behavior of underground rock masses treated with enzyme‐induced calcite precipitation (EICP) and an innovative biopolymer‐modified EICP (BP‐EICP). Abstract Biocementation is an innovative and sustainable technique for reinforcing weak and weathered rock masses in natural and ...

Investigating the coupling effect of loading rate and initial static shear stress on landslide and soil liquefaction within an energy-based framework

Geoenvironmental Disasters
Background Initial shear stress and loading rate are two critical factors influencing soil mechanical behavior. Their coupled effects, however, remain insufficiently understood, particularly in terms of strength evolution and deformation mechanisms ...

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

, 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.
