Abstract

Telecommunication conduits are facilities that houses and protects underground cables. Because those were mostly built from 1960s to 1980s, aging is progressing. In addition, conduit at this period is not sufficient in earthquake-resistance, and numerous damages have been confirmed in the past large earthquakes. As a method for repairing existing pipelines, lining technologies forming a coating film with a resin on inner surface of pipes are widely used. Since lining pipe itself has enough strength against earth pressure, effect expecting earthquake-resistances has been studied. The evaluation of seismic resistance of conduits with lining through analysis and experiments are described.
