摘　　要：文章结合长江南京以下深水航道建设一期工程潮汐径流河段的特点,针对新型的齿形及半圆型整治建筑物在工程中的首次应用,结合对开展的物模波浪断面试验成果的分析,建立了新型齿形构件波浪力的计算方法;提出了对半圆型混合堤的波浪力计算以T*和d/H进行划分,可采用不同计算方法的建议;文中还采用波浪在水流作用下变形的计算方法考虑了浪、流对混合堤结构的联合作用。Based on deepwater channel phase-1 project at the lower reach of the Yangtze River from Nanjing in which new toothed and semi-circular regulating structures were applied firstly, a new method has been established to calculate the wave force acting on the new toothed structure by analyzing the physical model experimental results of wave section. It is proposed to calculate the wave force on semi-circular composite dike by using different methods as per T＊ or d/H condition. A calculation method that considers the wave deformation caused by current has also been used, which applies to the joint force of wave and current on composite dike.
