Earthquake Engineering and Soil Dynamics, 2005
The occurrence of liquefaction in the form of decreasing shear resistance in saturated sands has been investigated under small departures from the undrained condition. Volumetric deformations are inevitable in field problems on account of the spatial variation in excess pore pressures generated during the earthquake shaking an d their subsequent ...

Liquefaction potential of reinforced sand
Geotextiles and Geomembranes, 1994Abstract A simple stress-controlled cyclic triaxial testing system developed for liquefaction testing is described. Using this system, a series of cyclic undrained triaxial tests were performed on sands with different densities and with different types of reinforcements to investigate the effect of reinforcement in enhancing resistance to ...

Statistical Analysis of Sand Liquefaction
Journal of the Geotechnical Engineering Division, 1981A consistent set of stochastic models is developed for the liquefaction resistance of a homogeneous mass of sand, such as a laboratory sample or small element of in situ material. A probabilistic model for liquefaction in the laboratory for undrained simple shear tests is developed first.

Liquefaction and post-liquefaction assessment of lightly cemented sands
Canadian Geotechnical Journal, 2020Post-liquefaction response of lightly cemented sands during an earthquake may change and become similar to uncemented sands due to bonding breakage. In the current study, the effect of degree of cementation on liquefaction and post-liquefaction behaviour of lightly cemented sands was studied through a series of cyclic and monotonic triaxial tests ...

Cyclic liquefaction strength of sands
Earthquake Engineering & Structural Dynamics, 1979AbstractThrough an energy approach, a model is proposed to predict the cyclic liquefaction strength of saturated sands in terms of their static shear strengths. Plots of cyclic liquefaction strength versus relative density and also versus modified standard penetration resistance are presented for various uniformity coefficients and different numbers of

Liquefaction Modeling for Biocemented Calcareous Sand
Journal of Geotechnical and Geoenvironmental Engineering, 2021AbstractA thermodynamics-based constitutive model is developed for calcareous sand treated by microbially induced calcite precipitation (MICP) to describe the effects of biocementation and its degr...

Liquefaction and Fabric of Sand
Journal of Geotechnical Engineering, 1984It is shown for simple shearing that the liquefaction and densification potentials of a cohesionless sample of sand do not necessarily decrease because of preliquefaction or because of large amplitude (drained) prestraining. In fact, in simple shearing, the resistance to liquefaction (undrained) or densification (drained) of a preliquefied sample ...

Influence of cementation on liquefaction of sands
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1989A study is reported which attempted to determine how cementation serves to resist liquefaction. Information on the relative influences of cementation and unit weight is reported since these two parameters sometimes produce similar effects. The study also determined what happens when soil is cemented in a nonhomogeneous manner, since this condition is ...

Liquefaction Screening—Non-plastic Silty Sands and Sands
2018Liquefaction screening of sands and silty sands using cone penetration resistance is a difficult problem. The presence of silt particles among the sand grains in non-plastic silty soils alter the intergrain contact density and affect cyclic resistance, flow and consolidation characteristics, and cone resistance of the soil.

Sand Liquefaction: Inelastic Effective Stress Model
Journal of the Geotechnical Engineering Division, 1982An effective stress numerical model for soil liquefaction, which provides interaction between shearing deformation and transient pore-water pressure development, is presented. Some attractive features of this one-dimensional model are the preservation of the inelastic soil character during shearing, the coupling between shear wave propagation and pore ...
