Influence of cementation on liquefaction of sands

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1989
A 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 and post-liquefaction assessment of lightly cemented sands

Canadian Geotechnical Journal, 2020
Post-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 ...

Liquefaction of Unsaturated Sands

International Journal of Geomechanics, 2016
AbstractRecent laboratory tests and field observations have revealed that unsaturated sands are susceptible to liquefaction. Systematic investigation of liquefaction potential of unsaturated sands is, however, lacking. In this paper, a coupled hydromechanical elastoplastic constitutive model for unsaturated sands is calibrated using available ...

Liquefaction and Fabric of Sand

Journal of Geotechnical Engineering, 1984
It 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 ...

Liquefaction Study of Cemented Sand

Journal of the Geotechnical Engineering Division, 1980
The paper describes some aspects of a liquefaction investigation of a variably cemented sandy profile. Due to the difficulty involved in extracting undisturbed samples for testing an evaluation was made of the use of standard penetration test results (i.e., blow counts) and samples in studying such profiles.

Liquefaction of Dilating Sand

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 ...

STATIC AND CYCLIC LIQUEFACTION OF SAND WITH FINES

Geotechnical Engineering for Disaster Mitigation and Rehabilitation and Highway Engineering 2011, 2011
A number of theoretical issues related to liquefaction are reviewed. Some findings of recent experimental studies at UNSW at ADFA are presented. These studies aim at capturing the influence of fines by an equivalent state parameter, establishing the linkage between static and cyclic liquefaction of sand with fines, and predicting the form of cyclic ...
