<p><P>PROBLEM TO BE SOLVED: To provide a pipeline crossing a fault with a means for improving earthquake resistance performance of the same in a relatively short term of construction work and at a low cost. <P>SOLUTION: A pipe formed with a buckling mode shape in a case where compressive force in a pipe axis direction acts is used as a structure for absorbing fault displacement. The pipe with the buckling mode shape is used in the pipeline in combination with straight pipes. During ground deformation, in the pipeline, only the buckling mode part absorbs extension (compression) deformation and therefore almost no force acts on the straight pipe parts. The problem is solved by the pipeline for a fault made of a steel pipe in which the buckling mode part and the straight pipe parts are connected. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
