Liquefied strength ratio from liquefaction flow failure case histories
Canadian Geotechnical Journal, 2002The shear strength of liquefied soil, su(LIQ), mobilized during a liquefaction flow failure is normalized with respect to the vertical effective stress (σ 'vo) prior to failure to evaluate the liquefied strength ratio, su(LIQ)/σ 'vo. Liquefied strength ratios mobilized during 33 cases of liquefaction flow failure are estimated using a procedure ...

Unified modeling of soil behaviors before/after flow liquefaction
Computers and Geotechnics, 2018Abstract Flow liquefaction of soil involves a phase transition process from solid to fluid. A constitutive model that can describe the soil behaviors of both the solid and fluid phases in a unified way was proposed. The constitutive model adopts a phase transition criterion to detect the onset of flow liquefaction and associates an elastoplastic ...

Wave-induced liquefaction and flow of subaqueous mud layers
Coastal Engineering, 1998Abstract In this paper, results of laboratory experiments on wave-induced liquefaction and transport of mud are presented. Wave-induced stresses inside the bed at the onset of liquefaction are shown to be just larger than the yield strength of the bed, which is determined independently with sounding tests.

Large scale sand liquefaction flow slide tests revisited
2012Massive failure of submerged slopes form a major threat for many dikes along estuaries in the Netherlands, the subsoil of which consists of alternating layers of loosely packed and more densely packed sand. Static liquefaction in the loosely packed sand plays an important role.

Onset Condition for Liquefaction and Consequent Flow
1996Abstract In the preceding chapters, laboratory testing on reconstituted samples has been recognized as a useful tool for making the most conservative estimate of the residual strength of in situ sands. A similar argument may be developed as to the cyclic strength controlling the triggering of liquefaction.

An Entropy Flow Optimization Technique for Helium Liquefaction Cycles
1984Several potential applications of superconducting technology require large size refrigerators/liquefiers for cooling. The capital cost of such large size refrigerators is small compared with the operating cost. Therefore there is an emphatic need for highly efficient refrigerators.

Triggering of liquefaction flow slides in coastal soil deposits
Engineering Geology, 1988Abstract Liquefaction flow slides have been observed in coastal soil deposits throughout the world. The causes of many of these slides have never been well understood. The materials involved in and circumstances surrounding eight reported liquefaction flow slides are reviewed and compared.
