Abstract

Damage mechanism for buried pipelines of telecommunication systems subjected to the 2011 off the Pacific coast of Tohoku earthquake was clarified. Failure modes for 359 data were classified into 5 types. Relationships between the failure modes and indices of ground excitations such as peak ground acceleration, peak ground velocity and instrumental seismic intensity were revealed. The characteristics of damage ratio to reflect the differences in damage mechanisms of buried pipes affected by ground shakings and liquefaction were discussed.
