【 摘 要 】

The principle of resonant structures is briefly described. These hydraulic resonators, which have been patented by Eleotricite de France, act as reflective structures for a range of wave periods encompassing their period of resonance, without obstructing the passages like a jetty. The originality of these structures lies in the fact that the periodicity of the waves is used to reflect them.Some dispositions of resonant structures are described: basins having a length equal to a quarter of the wave length, resonators similar to pipes of different types, one of them having a period of resonance independent of the variations of level due to the tides.Applications to harbor problems have been studied at Chatou. One of them concerns the protection of a look and of an inner harbor, the other the protection of a harbor in which resonant struotures have been used to complete the action of ordinary struotures for a certain range of wave periods.
