| Research Abstract |
A pipe-in-pipe filled with sand was developed as an innovative structure for chilled gas pipeline in northern cold regions where a plenty of natural gas is reserved. As a result of the study, it is confirmed that the pipe-in-pipe can comply with environmental change due to increased ductility by sand because it allows large deformation. In addition, self recovery in flexural rigidity and anti-leaking becomes possible by artificial freezing and thawing of surrounding soil.
