Abstract

The damage induced by seismic events is well known among the civil engineering, geological and seismological community. Seismologists and geologists who study this hazard at a deeper level are concerned more with the history and cause of earthquake events rather than their effects. When seismic energy is released during an earthquake it passes from the bedrock, then through the soil and to the sub structure through which it is transmitted to the superstructure. Liquefaction phenomenon is a consequence of earthquake induced pore water pressure in the soil due to this released energy. Various deterministic and probabilistic based methods have been developed in the recent past after various case histories. It is crucial to understand the performance of critical structures such as pipelines, road networks, nuclear reactors etc during liquefaction. The current chapter majorly focuses on the liquefaction assessment using numerical modeling.
