PERFORMANCE OF DOLOS BLOCKS IN AN OPEN CHANNEL SITUATION

[摘要] Tests on 100 gm model dolos units on the bed of an open-channel under steady state turbulent flow reveal that the dolos unit has no inherent interlocking property that would make it preferable to ordinary armour stone of the same weight in resisting movement. However interlocking can occur when dolos units are placed on a slope since the natural angle of repose of dolos units is much greater than that of ordinary armour stone, thus accounting for the enhanced Kp of dolosse in a breakwater situation.
