㩷 Focused on the bedding effects of existing host pipes on the flexible liners for the pipe
rehabilitation, in this study, earth pressure and deformation behavior of flexible liners for differentdeterioration conditions of the host pipes were investigated through a full-scale loading test, aseries of centrifuge model tests and FEM numerical analysis. The bedding effects of the hostpipes were quantitatively analyzed. It was clarified that the external loads acting on the flexibleliners were mitigated, since the deteriorated host pipe partially supported the external loads inresponse to the deterioration degrees, such that the bending strain and vertical deflection of theflexible liner were restrained. A reasonable design methodology for pipe rehabilitation shouldreflect such bedding effects.
