Abstract
In order to ensure the safe operation of the offshore photovoltaic power plants,the wave dissipation facilities are arranged around the site area to reduce the impact of waves on the site structure.From practical engineering,a transparent wave dissipation plate structure scheme is adopted for the periphery of offshore photovoltaic areas.The wave tank model tests are conducted to study the wave dissipation rate and wave force under three combination conditions(50-year high tide level combined with 50-year high wave,50-year high tide level combined with 25-year high wave,and 25-year high tide level combined with 25-year high wave).The results show that:under the three working conditions,the wave dissipation rates of the significant wave height Hs and accumulative frequency 1% wave height H1% are 11.9% and 11.3% ,7.0% and 6.8% ,6.7% and 6.6% ,respectively,with significant wave dissipation effect;under the three working conditions,the single width forward wave forces(maximal value.fy,max and accumulative frequency 1% value.fy,1% )of the permeable wave dissipation plate structure are 36.88 kN/m and 35.64 kN/m,23.89 kN/m and 23.29 kN/m,19.25 kN/m and 18.64 kN/m,respectively,effectively ensuring the safety of the wave dissipation plate structure.The proposed structural type scheme of the permeable wave dissipation facilities provides reference for ensuring the safety and economy of offshore photovoltaic power engineering structures.
