Abstract
- For the direct measurement of the wave forces acting on a rubble mound breakwater in a wave flume, a breakwater frame model was devised. The core part in the model was filled with specially shaped empty polyhedrons instead of natural stone to reduce total weight. Natural armor stones were adopted for the cover layer and filter layer on the front slope of this model. Horizontal and vertical components of wave force were measured using a load cell meter. Water level on the slope was measured using the inclined wave gages installed along the slope of the model. Water elevations at the two points on the slope and wave pressures along the front slope and along the model bottom were measured. Results show that horizontal components of wave forces evaluated from the two different methods coincide fairly well. However, vertical components of the wave forces measured directly with the load cell meter are much smaller than those integrated using pressure values. Calculated wave forces using measured pressure were compared with those calculated using the linear equations of partially reflected wave-form on the slope suggested by Goda (2002).
