Description

 In the new runway and water passage under construction at Naha Airport, the water passage is composed of box culverts. To clarify the propagation of wave pressure inside the box culverts, a large-scale hydraulic experiment and a numerical simulation were conduc6ted. The results of the study clarified, the following matters. Wave pressure propagates rapidly inside the water passage, and propagates not only inside the box culverts but also inside the mound and backfill-stones area surrounding the box culverts. Wave pressure inside the backfill-stones area can cause migration of backfill soil through breaks in the geotextile sheet used to stabilize backfill.
