Extraction Force Xbloc: Model Tests

This study describes the influence of the slope angle of a breakwater slope, the density of the concrete of the Xbloc armour unit, the vertical position of the Xbloc on the breakwater slope and the roughness of the under layer of the breakwater on the extraction force of an Xbloc armour unit. By testing the extraction force, indirectly the influence of all parameters above on the Xbloc unit interlocking capacity can be described. This research has been done by doing model tests with small scale Xbloc units.
