Abstract

Earthquake-induced liquefaction causes damage to structures and property and is of major concern to engineers. To estimate damage during liquefaction, it is necessary to go one step beyond the evaluation of liquefaction potential. Damage is a highly controversial subject due to its qualitative nature. One extremely conservative limit case that is considered in this paper is liquefaction as a subsidence problem. This case could be visualized as the collapse of a tunnel in a soft deposit and its consequences. For a liquefaction problem this case can be modeled as a subsidence problem where all or part of the liquefied soil volume has flowed away from beneath the foundation, creating a void. Since a considerable number of parameters are involved in the problem and a considerable amount of uncertainty is expected in many of them, a risk-based damage estimation is essential. The development of such a model is the subject of this paper.
