Seismic risk management for water pipeline networks - Seismic Risk Analysis and Management of Civil Infrastructure Systems - page 649

• Seismically strong segmented pipe joints have to be supplied at low cost,

because partial replacement of pipe joints is not effective. A complete
replacement of old pipes over a limited period will be useful to guard
against any future strong earthquakes.

• Since peak ground deformation results in signifi cant failure of buried

pipelines, further study should be devoted to the seismic design of
buried pipelines crossing liquefaction-sensitive areas or active fault
zones.
