A LIQUEFACTION FAILURE OF A WASTEWATER INTERCEPTOR
A large diameter wastewater interceptor line failed during a moderate earthquake. Two sections of the line rose from one to three feet above its original grade. An investigation showed that the primary cause was liquefaction of the granular backfill in locations where drainage was inhibited. The ground motions generated by the earthquake were moderate, however there is a possibility that there was amplification of the ground motion in the immediate failure area.
