The Applicability of Code for Characteristic Depth in Liquefied Evaluation

Abstract:

In the Initial impression of seismic code liquefaction conditions, when sand overburden depth is deeper than the characteristic sentenced, it will not consider the liquefied impact, in this paper use recent liquefied sites survey data to examine the liquefaction evaluations applicability. Using 1995 Kobe earthquake in Japan and 1999 Taiwan Chi-Chi earthquake liquefaction survey data, can find the characteristic depth will produce misjudgment and dangerous result; using 2011 New Zealand Ms6.3 earthquake liquefaction survey data, preliminary estimates by liquefaction characteristics depth will be make 65% of the liquefied sites misjudgment liquefaction and serious danger. Therefore, the depth of liquefaction characteristics of initial conditions for code value is not applicable, need to study to improve.
