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 different deterioration conditions of the host pipes were investigated through a full-scale loading test, a series of centrifuge model tests and FEM numerical analysis. The bedding effects of the host pipes were quantitatively analyzed. It was clarified that the external loads acting on the flexible liners were mitigated, since the deteriorated host pipe partially supported the external loads in response to the deterioration degrees, such that the bending strain and vertical deflection of the flexible liner were restrained. A reasonable design methodology for pipe rehabilitation should reflect such bedding effects.
