Model Experiment for Influence of Sheet Pile Characteristics on Mechanical Behavior of Buried Flexible Pipe
Publication: Pipelines 2020
ABSTRACT
Large diameter pipelines in Japan are commonly buried in open-excavation using sheet piles because of the limited work sites and poor ground conditions. However sheet pile extraction is likely to cause significant damage to buried flexible pipes. In the Japanese current design guidelines for irrigation pipelines, influences of the sheet pile conditions have been ignored. In this study, model experiments were conducted to clarify the influences of ground density and sheet pile characteristics (the friction of the sheet pile, and the scale of the voids after sheet pile extraction) on the mechanical behavior of the buried pipes. Moreover, PIV (particle image velocimetry) analyses were carried out to evaluate the displacement of the backfill material around the pipe. The experimental results revealed that the deformation of the model pipe became large when the ground density decreased, and the sheet pile characteristics influenced the buried pipe during sheet pile extraction.
