Unconfined Compressive Strength Testing on Expansive Clay Soils Stabilized with Cement and Lime
Rekayasa SipilSoil stabilization offers an alternative solution to overcome the problem of expansive clay soil characteristics. Unconfined compressive strength tests were conducted on original and expansive clay soils containing cement and lime to investigate the ...

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{{

Deep Underground Science and Engineering, EarlyView.Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Microstructural and UCS behavior of clay soils stabilized with hybrid nano-enhanced additives
Reviews on Advanced Materials ScienceIn this study, both individual and hybrid effects of industrial wastes (silica fume, fly ash), fibers (glass and basalt) and nanoparticles (nano SiO2, nanoclay) mixed with clay at different ratios were investigated in detail at macro and micro levels at ...

Deep Underground Science and Engineering, EarlyView.Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling
