Seminar - Samanthika Liyanapathirana - Assessment of Soil Liquefaction incorporating Earthquake Characteristics

Wednesday, April 11, 2001, 1.10 - 1.40 pm
Civil Engineering Lecture Room 3

Abstract

A new method for assessing the liquefaction potential of a soil deposit subjected to an earthquake loading is presented. In most of the currently available methods of assessing liquefaction potential, the nature of the earthquake and the dissipation of the pore water pressure during the earthquake loading are not taken into account. In the method presented, the nature of the earthquake is included in the parameter V which is the gross area under the input acceleration record. By analysing 15 earthquake records from different parts of the world, a method is outlined to assess the effects of the dissipation of pore water pressures and the nature of the earthquake on the liquefaction potential.
