ABSTRACT
In this study, numerical analysis was applied to investigate the mechanical behavior of separated pipe joint rehabilitated by the Cured In Place Pipe (CIPP). The numerical model was calibrated by the laboratory test results, then applied to simulate the rehabilitated pipelines with various geometries and loading conditions. The influence of control factors, i.e. backfill, interface, etc., on CIPP rehabilitation performance was also analyzed in details. The results of this study suggest that the CIPP could improve the separated joint to certain extent, and the findings could be applied in design optimization and guideline development.
