Study on SPF Application for Ground Settlement
Publication: Lifelines 2022
ABSTRACT
Ever since 1906 San Francisco Earthquake, earthquake damage to buried pipelines due to fault movement, liquefaction, and ground settlement has been seen in large-scale earthquakes. Steel Pipe for Fault (SPF) settlement type was developed to absorb ground displacement and prevent water leakages at connections in ground structures and buried pipelines in order to maintain water flow without cracks, even if ground settlement occurs. The development of this SPF is based on the technology of the SPF original type, which is a solution for pipelines in fault zones. Since the pipe thickness of SPF settlement-type is the same as that of the main pipe, the reaction force is larger when compared to that of general flexible pipes. In order to reduce the reaction force, numerical analysis and modeling were carried out to improve SPF shape. This paper shows several case studies of SPF settlement type in Japan.
