The action in hydro-wave flume on 3 types of partly permeable wave-protective structures by surface waves was investigated.

The first type of structure was a pier having two pilings and a grillage (horizontal top plate). The space under the pier from rear of piling to the center of the grillage across-track direction was filled up with concrete blocks. The barriers (vertical plates) were hanged on the two pilings. At that case the rear barrier came into contact with the concrete blocks. The right side barrier was partly submerged in fluid.

The second type of structure differs from the first type with slits at the right side barrier. Area of the slits was 20 percent of submerged part of the barrier.

The third type of structure was the ferroconcrete frame filled up with stone layers, concrete blocks, and hexabits. The wavemaker produced the regular waves having large amplitude.

The wave-permeability and wave-reflectivity abilities of the structures and the force action taken up by the structures were studied. The simple numerical model of water-waves and structure’s interaction were elaborated. Its comparison with the experimental data is fulfilled.

The results of the research are used in designing of wave-protective structures in harbors.
