Usually, the bridge used to traverse rivers, channels and straits is a fixed type. However in cases where the seabed of a thick layer of soft ground, a floating bridge is often more suited than a fixed bridge. This study proposed a system for anchoring a floating bridge with submarine cable to create a floating bridge suitable for places where ground subsidence occurs. Using an experimental tank, the bridge's motion characteristics while exposed to waves were tested and a numerical analysis was performed.
As the floating bridge anchored with submarine cable is a newly conceived system, the safety and usability in locations that have waves were verified by means of experiment and numerical analysis. It was found that the floating bridge with submarine cable system was highly suitable for locations where there was significant ground subsidence.
