Flow Liquefaction Instability as a Mechanism for Lower End of Liquefaction Charts
Journal of Geotechnical and Geoenvironmental Engineering, 2017The 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. These charts are based on case histories of past earthquakes and have proven to be useful while evaluating ...

Liquefaction of coal in a flowing-solvent reactor
Fuel, 1991Abstract A flowing-solvent liquefaction reactor has been used to examine the primary solubilization potential of a range of coals. The reactor configuration allows the suppression of secondary reactions by sweeping the heated zone with a continuous flow of solvent. The design of the system combines low thermal inertia and direct electrical resistance

Liquefaction flow slides in large flumes
International Journal of Physical Modelling in Geotechnics, 2019Liquefaction 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. The programme included more than a hundred tests in large- and medium-sized flumes on submerged, loosely packed sand bodies.

Liquefaction and Flow Failure During Seismic Exploration
Journal of Geotechnical Engineering, 1990A case history and analysis of a flow slide due to soil liquefaction is presented. The failure was triggered by vibratory tampers conducting a seismic reflection survey on a roadway embankment in Michigan's Upper Penninsula. Postfailure investigations included a survey of construction records, in situ and laboratory tests, and replication of the input ...

Liquefaction flow slide at horizontal ground
2005A liquefaction flow slide is an instability in loosely packed saturated sand or silt after liquefaction under monotonic loading. The conditions for such a flow slide are discussed. The relevance of these conditions is illustrated by application to slope failure.

Constitutive Modeling of Flow Liquefaction and Cyclic Mobility
Computer Simulation of Earthquake Effects, 2000Flow liquefaction is due to contractive response of loose granular soils, while cyclic mobility is related to both contractive and dilative response of granular soils. These two failure mechanisms may occur in a single soil, depending on the density and confining pressure applied.

Liquefaction and flow failure during earthquakes
Géotechnique, 1993Two aspects of seismically-induced liquefaction are discussed which are of vital engineering significance: the triggering condition and the consequences of liquefaction. The triggering condition is examined with respect to liquefaction analysis, note being taken of the onset condition which is governed by cyclic strength.

Liquefaction flow behavior of Guamo sand
2015In soil mechanics there are many unknowns about the behavior of materials and even more great uncertainty generated sands, due to its gradation and shape of the grains is sometimes difficult to know their behavior and especially when trying to study by tests in laboratory.

Parameters describing flow liquefaction of soils
2005The paper presents the results of comprehensive laboratory test programme carried out on various soils. Monotonic undrained triaxial tests were executed on specimens subjected to isotropic and anisotropic consolidation. Some parameters based on mean effective stress values at specific stages of a test were used for the sake of quantitative analysis of ...

Seabed instability due to flow liquefaction in the Fraser River delta
Canadian Geotechnical Journal, 1997Abstract: 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 1985 at the mouth of the Main Channel of the Fraser River has been carried out using steady ...
