分层斜坡越浪式波能发电装置结构受力试验研究

An Experimental Study on Structural Stress of Slope-type OWEC of Double Reservoirs

分层斜坡越浪式波能发电装置作为一种重要的波能转换型式,在开发利用波浪能的同时,可与防波堤或护岸工程相结合,将海岸工程的被动消能变为主动吸能,提高综合效益。在实际工程应用中,分层斜坡越浪式发电装置引浪面在波浪荷载作用下的安全性成为首要问题,由于其引浪面与防波堤或护岸的护面对水体磨阻影响不同,因此水体对结构的作用力不同,已有的斜坡式防波堤所受波浪荷载的研究无法用于指导分层斜坡越浪式发电装置引浪面的结构强度设计。通过水工物理模型试验,对分层越浪装置引浪面在不同波况条件下的结构受力进行研究分析,获得越浪装置引浪面上点压力及波浪力的分布规律,为装置的结构设计提供理论指导及设计支持。

As an important type of wave energy convertor,the slope-type overtopping wave energy convertor(OWEC)can be installed together with breakwater or revetment,which can not only turn passive energy dissipation into active energy absorption in the development and utilization of wave energy,but also enhance comprehensive benefits.In practical engineering application,the safety of the wave-guide slope surface of OWEC under the action of wave load becomes one of the most important issues.Because the influence of the slope surface of OWEC on the water resistance differs from that of the armor of breakwater or revetment,the acting force of the water body on the structure is different.The existing studies of the wave load on slope-type breakwater cannot be applied for guiding the design of the structural strength of the wave-guide slope surface of OWEC.In order to study the structural stress of the wave-guide slope surface of OWEC,hydraulic physical model experiments are conducted under different wave conditions,by which a distribution law of the point pressure and the wave force on the wave-guide slope surface of OWEC is obtained,providing theoretical guidance and design support for the structural design of OWEC.
