Abstract
In this study, the performance of underground water pipeline system affected by earthquakes is examined by using data acquired after MW 6.2 February 22, 2011 earthquake in Christchurch, NZ. Water pipeline repair rates, expressed as repairs/km, for different types of pipe are evaluated inside the areas of which liquefaction induced by permanent ground deformation was observed and assessed relative to differential settlement and lateral ground strain, calculated from high resolution LiDAR data acquired before and after each seismic event. The earthquake performance of underground water pipeline systems associated with permanent ground deformation is summarized in this paper. The results show that highly ductile polyethylene water pipelines has a high earthquake performance.
