Abstract

The recent failure of a coastal buried pipeline along the Italian coast is presented. Extensive initial investigations to assess failure causes are conducted and several shreds of evidence are identified leading to wave-induced liquefaction as the main source of failure. This thesis is subsequently confirmed through the application of two known analytical models, i.e. Ishihara and Yamazaki 1984 and Sumer et al., 2012. The results show that despite the rather inexpensive computational cost of the models, they can be successfully used to identify the area affected by the wave-induced liquefaction with good agreement with field observation.
