ABSTRACT
This chapter addresses the earthquake performance of buried pipelines. Buried pipelines are vital to modern society, carrying water, gas and liquid fuels and other materials to a city’s residents, and conveying wastewater away. Historically, buried pipelines have sustained major damage in past earthquakes (Figure 23.1), so this chapter begins with a review of buried pipeline performance in past earthquakes. We then examine how seismic hazards are quantified for buried pipelines, the failure mechanisms of buried pipelines, and the response of
continuous
and
segmented
pipelines to wave propagation and various types of permanent ground deformation. The final section addresses various mitigation measures.
