Seismic vulnerability and extensive damage to underground lifeline network, causing significant life and economic losses, have been observed and documented in past earthquakes. Seismic retrofit of critical underground pipelines has become an urgent need of our society to improve the performance and serviceability of these critical lifeline systems as well as to enhance public safety. The cured in place pipe (CIPP) lining technology consists of installing flexible polymeric liners with thermosetting resin inside existing pipelines. Compared to traditional expensive and disruptive excavation and replacement of aging and structurally unsound pipelines, CIPP lining technology provides an economic and environmentally friendly alternative for pipeline rehabilitation. However, the lack of verification and quantification of the seismic performance of CIPP liner-reinforced pipelines under transient ground deformations (TGD) remains a critical deficiency in current practice. An experimental study was performed on water-pressurized ductile iron (DI) pipelines, 150 mm (6.0 in.) nominal diameter and 9.14 m (30 ft.) nominal length, reinforced with two different types CIPP liners commonly used in pipeline rehabilitation. This paper compares the behavior of DI pipelines strengthened with different types of CIPP liner under quasi-static loading and also investigates the seismic responses of CIPP liner-retrofitted pipelines under transient ground deformations induced by seismic wave propagations near the ground surface. The test results indicate that both types of CIPP liner provide substantial longitudinal strength to the joints of DI pipelines and improve significantly their seismic behavior under high intensity transient ground deformation.
