Seismic analysis of buried flexible pipes

Research output: Contribution to journalArticlepeer-review


A simplified pseudo-static strain analysis method is proposed to identify the main causes of the transverse buckling of buried structures, such as culverts, during earthquakes. The proposed method is based on a case history of a 2.4-m diameter corrugated metal pipe at the Lower San Fernando Dam, which failed during the 1994 Northridge earthquake. The analysis considered factors such as static overburden pressure, peak ground velocity, liquefaction induced ground displacement, pore pressure buildup, and nonlinear soil response. The analysis suggests that the pipe failure was mainly caused by the large near-fault ground motions and a reduction in stiffness of embedding soils due to pore pressure buildup, without complete liquefaction.
