可渗潜堤波浪透射系数试验研究

针对实际工程中广泛应用的潜堤结构,采用断面物理模型试验的方法,对规则波作用下波浪与可渗潜堤的相互作用进行研究,讨论了淹没水深R_C与波高H之比R_C/H、波高H与周期的平方T~2之比H/(gT~2)、堤顶宽度B与波长L之比B/L、潜堤坡度m以及堤心石粒径D与波高H之比D/H等无因次参数与潜堤堤后透射系数K_t的关系。在前人研究成果的基础上,提出了改进的经验计算公式,为潜堤的工程设计提供理论参考。

Experimental study on wave transmission coefficient of permeable submerged breakwater

For the structures of submerged breakwater which are widely used in practical engineering,this paper studies the interaction between wave and permeable submerged breakwater under regular waves through a series of sectional model tests.The relationships between the transmission coefficient of submerged breakwater and dimensionless factors are discussed.These factors include the ratio of submergence depth to wave height RC/H,the ratio of wave height to the square of wave period H/(gT2),the ratio of crest width to wavelength B/L,the ratio of the grain diameter of core material to wave height D/H and the slope of submerged breakwater m.Then the improved empirical formulas on the basis of previous researches are proposed to provide theory reference for the design of submerged breakwater.
