Liquefaction resistance of partially saturated sands

, 2022
Abstract Partially saturated sands with occluded gas bubbles may occur naturally in the field or can be created artificially as a way of mitigating liquefaction effects. The gas bubbles in pore spaces significantly alter the bulk modulus of pore fluid and consequently affect the excess pore pressure generation and liquefaction behavior of sands.

Effect of cement content on the static and dynamic liquefaction resistance of fine tailing

Case Studies in Construction Materials
Cement tailings storage (CTS) in goaf may experience static and dynamic loading, such as rock stress, mine earthquake and blasting stress. When subject to dynamic loading, the risk for liquefaction of CTS may cause goaf barricade instability.

LIQUEFACTION RESISTANCE OF SAND MATRIX SOILS

Jurnal Teknologi, 2015
Numerous researches have been focusing on the roles of fines in liquefaction resistance of sand matrix soils (sand dominant soil that contains little presenting fines). It has been reported that the presence of plastic fines would either imposed additional liquefaction resistance of sand matrix soils or caused reduction to the liquefaction resistance ...

Pore Water Pressure Generation and Energy Dissipation Characteristics of Sand–Gravel Mixtures Subjected to Cyclic Loading

Geotechnics
At least 32 case histories have shown that liquefaction can occur in gravelly soils (both natural deposits and manmade reclamations) during severe earthquakes, causing large ground deformations and severe damage to civil infrastructures.

Effectiveness of sheet pile enclosure with drainage ability as liquefaction countermeasure for river levees

Soils and Foundations
Sheet-pile enclosures are often employed as liquefaction countermeasures for river levees in Japan. However, the stiffness of the sheet piles alone is often insufficient to maintain levees on liquefied foundation soil high enough to prevent overflooding.

Relationship between void characteristics and re-liquefaction resistance: An image analysis study

Soils and Foundations
To scrutinize the impact of void characteristics on re-liquefaction resistance, a series of constant-volume cyclic bi-axial tests was conducted on an assembly of plastic rods. The first and second liquefaction stages involved the application of isotropic
