Criterion for flow liquefaction instability

Acta Geotechnica, 2013
This study describes a general liquefaction flow instability criterion for elastoplastic soils based on the concept of loss of uniqueness. We apply the criterion to the general case of axisymmetric loading and invoke the concepts of effective stresses ...

Unified modeling of flow liquefaction and cyclic mobility

Soil Dynamics and Earthquake Engineering, 2000
Flow liquefaction and cyclic mobility are two different phenomena that are encountered during strong earthquakes. Flow liquefaction is associated with the contractive behavior of loose granular materials and cyclic mobility is associated with the ...

Assessing Liquefaction Flow Slides: Beyond Empiricism

, 2018
The liquefaction flow slide is an important failure mechanism for under water slopes composed of sand.The failure of the sand body is the result of liquefaction of loosely packed sand, which suddenly looses a large part of its strength and starts ...

Breaching and liquefaction in subaqueous retrogressive flow slides

Canadian Geotechnical Journal, 2022
Although retrogressive flow slides in subaqueous sandy slopes can be very large and cause substantial damage, the failure mechanisms of such slides are not very clear yet.

The influence of clayey soil hardpan layers in turbid plumes from water flow [PDF]

Scientific Reports
To investigate the formation mechanism of hardpan layers in liquefied silty soils, this study simulates external physical disturbances using a controllable rotating wheel and observes the internal flow field evolution through Particle Image Velocimetry ...

Liquefaction flow slides in large flumes

International Journal of Physical Modelling in Geotechnics, 2019
Liquefaction flow slides in sand have been investigated during an extensive experimental research programme during the period 1973–1977 on behalf of the design of the storm surge barrier in the Oosterschelde estuary.

Seabed Instability due to Flow Liquefaction in the Fraser River Delta

Canadian Geotechnical Journal, 1997
: Liquefaction failures of loose sand deposits can be a major concern for the stability of coastal structures. an investigation to evaluate the possible contributions of different triggering mechanisms in a major liquefaction failure that occurred in ...

Flow Liquefaction Instability as a Mechanism for Lower End of Liquefaction Charts

Journal of Geotechnical and Geoenvironmental Engineering, 2017
The state-of-the-practice uses the “simplified procedure” for evaluating liquefaction susceptibility of soils. Based on this procedure, liquefaction charts have been developed that correlate soil resistance to earthquake-induced stresses.

Mechanics of origin of flow liquefaction instability under proportional strain triaxial compression

Acta Geotechnica, 2016
We define a flow liquefaction potential for determining flow liquefaction susceptibility during proportional strain triaxial compression . The flow liquefaction potential is a function of inconsistency between the natural dilative tendency of the soil ...
