Active fault countermeasure piping design method

摘要

PROBLEM TO BE SOLVED: To provide an active fault countermeasure piping in which its structure is simplified and it can be easily designed.SOLUTION: An active fault countermeasure piping 1 is constituted by a linear line type piping 10 buried in soil 100 having an active fault 110 and a partial bent piping 10. There is provided an active fault countermeasure part 20 not installed in a static layer 111 of the active fault 110, but arranged in a motion layer 112 of the active fault 110 so as to absorb axial force acted on the piping 10 installed in the motion layer 112 and to absorb axial force acted on the piping 10 arranged in the static layer 111 in order to prevent stored item stored in the piping 10 from being leaked out of the piping when the active fault 110 is moved at the time of earth crust motion.SELECTED DRAWING: Figure 1
