Banc de qualification pour une application de la méthode simplifiée d'analyse du risque de liquéfaction des sols à partir des essais in situ SPT et CPT

Abstract : Soil liquefaction triggering during earthquakes is usually evaluated by the SPT or CPT based simplified method. This method, first proposed by Seed and Idriss in 1971, allows evaluating the factor of safety against liquefaction. Several states of the art have been published over the years, the later being at the NCEER' 1997 workshop (Youd et al., 2001). Practical utilisation of this state of the art provides results that are user-dependant. Whereas all the questions raised by the NCEER's practical utilisation are not exhaustively addressed in this paper, it has being found interesting to share the current practices. This paper provides the results of two benchmarks that put into practice the SPT and CPT based simplified method.
