Model Experiments for the Mechanical Behavior of Buried Rehabilitated Pipes under Eccentric Loading
Trenchless rehabilitations have often been used for repairing aging irrigation pipes. However, in the Japanese design standard for irrigation pipes, the design of the rehabilitations is not prescribed. Many of past studies have not dealt with the mechanical behavior of rehabilitated pipes under eccentric loading, and the behavior has not been understood. In this study, for investigating the mechanical behavior of the rehabilitated pipes under eccentric loading, model experiments and FE-analyses were conducted. In the experiments, the rehabilitated pipes were modeled by placing the aluminum segments around the polyvinyl chloride (PVC) pipes, and the pipes were loaded with the air-bag. The results indicated that the only liners under eccentric loading deformed in oblique directions with the shift of the loading positions. On the other hand, the deformations of the liners with the host pipes were dependent on both the directions of loads acting on the liners and the damage states of the host pipes.
