WebA 'flow failure' may initiate if the strength of the soil is reduced below the stresses required to maintain the equilibrium of a slope or footing of a structure. This can occur due to monotonic loading or cyclic loading, and … WebThe 2010 Maule earthquake was a megathrust event that occurred along the Peru–Chile Trench. The earthquake source can be modelled as a fault with two asperities with different areas and strengths. By employing a discrete fault model, where asperities are the basic elements, the event can be described as a sequence of three …
WebAug 15, 2024 · These events are usually interpreted to reflect flow-induced resonance of fluid-filled cracks or choked flow of ... In contrast, the deep brittle-failure earthquakes since 2006 are concentrated in discrete swarms lasting 12 to 36 hours each, which individually show clear migration of hypocenters over the course of a few hours (Fig. 2, B to F ... WebMar 19, 2024 · Several permanent ground movements are associated with liquefaction during earthquakes, such as ground oscillation, flow failure, loss of bearing capacity, lateral spreading, subsidence, and buoyancy. Buoyancy and lateral spreading are major critical effects for pipelines. A simplified scheme with possible induced mechanism is …
WebMay 3, 2024 · Loose granular soil, when subjected to shearing, may collapse rapidly to large strains with a very low residual strength. This flow-type failure, known as flow slide or flow liquefaction, is a major concern in geotechnical applications involving slopes, dams and embankments. A fundamental understanding of the flow liquefaction phenomenon has … WebOct 1, 2014 · A liquefaction flow failure requires a triggering mechanism to initiate liquefaction and undrained strain-softening. When a soil is sheared, its volume may increase (dilate) or decrease (contract) depending on its density and the magnitude of the effective stress applied on the soil. ... Liquefaction and flow failure during earthquakes ...
WebEarthquakes, blasting, and pile driving are all example of dynamic loads that could trigger flow liquefaction. Once triggered, the strength of a soil susceptible to flow liquefaction is no longer sufficient to withstand the …
