ABSTRACT
ABSTRACT: During the 1999 Chi-Chi Earthquake, a site named Wu-Feng very close to the fault rupture in central Taiwan has suffered serious damages caused by soil liquefaction induced ground failures. Detailed case study of Wu-Feng is reported in this paper in an effort to investigate both failure causes and damage types. In this paper, the authors first present soil condition and characterization of the near fault strong ground motion of Wu-Feng. Secondly, both reconnaissance and surveyed results of liquefaction induced ground failures are presented. Lastly, conclusions on factors that possibly contribute to such extensive ground failures and future research suggestions are provided. Progress of presented study is hopefully to improve our understanding on liquefaction induced ground failures caused by strong ground motions.
