Abstract:A series of regular and irregular wave experiments are conducted to study the reflective and transmitting performances of quarter circular breakwater (QCB) in comparison with those of semi-circular breakwater (SCB).Based on regular wave tests,the reflection and transmission characteristics of QCB are analyzed and a few influencing factors are investigated.Then,the wave energy dissipation as wave passing over the breakwater is discussed based on the hydraulic coefficients of QCB and SCB.In irregular wave experiments,the reflection coefficients of QCB and their spectrums are studied.Finally,the comparisons between the experimental results and numerical simulations for QCB under regular and irregular wave conditions are presented. 作者: Author: SHI Yan-jiao[1]  WU Mi-ling[2]  JIANG Xue-lian[1]  LI Yan-bao[3] 作者单位: Tianjin Key Laboratory of Soft Soil Characteristics & Engineering Environment, Tianjin Institute of Urban Construction, Tianjin 300384, ChinaWuhan Harbour Engineering Design and Research Co.
