PROBLEM TO BE SOLVED: To provide a pipeline structure which enables a pipeline disposed while being buried in a fault zone or the like to deal with (absorb) big ground displacement (fault displacement) caused by moving a fault, and a pipeline structure program for supporting a design of the pipeline structure.SOLUTION: The pipeline structure indicates a structure of the pipeline that is disposed while being buried, and includes two thimbles 51 and a plurality of short pipes 52. The plurality of short pipes 52 are connected by a joint structure. The two thimbles 51 are disposed to hold a zone in which the fault displacement is estimated, therebetween, thereby dealing with (absorbing) the ground displacement in a pipe axis direction. The plurality of short pipes 52 are connected by joints more than the number of joints in arranging long pipes 54. The number of joints is increased, thereby more easily dealing with (absorbing) the ground displacement in a direction right-angled to the pipe axis. The number of joints in the pipeline structure and a distance between the thimbles are calculated by an arithmetic operation of a computer in accordance with a fault condition, and pipeline structure data are outputted in accordance with a calculation result. |
