Surface Manifestation of Liquefaction
Soil liquefaction is a major cause of damage during earthquakes. Over the past decade, major advances have occurred in both understanding and practice with regard to assessment and mitigation of hazard associated with seismically induced soil liquefaction. Today, the area of “soil liquefaction engineering” is emerging related issues evolved initially in the wake of the two as a semi-mature field of practice in its own right. This area devastating earthquakes of 1964; the 1964 Niigata (Japan) and now involves a number of discernable sub-issues or sub1964 Great Alaskan Earthquakes. Seismically-induced soil topics including, Assessment of the likelihood of “triggering” or initiation of soil liquefaction, Assessment of post-liquefaction strength and overall post-liquefaction stability, Assessment of expected liquefaction-induced deformations and displacements, Assessment of the consequences of these deformations and displacements, Implementation (and evaluation) of engineered mitigation, if necessary.
Our presenter, Dr. K. Onder Cetin will discuss recent advances in seismic liquefaction engineering in the upcoming TVSeminar on July 27th, 2021.
