摘　　要：对沉箱式防波堤动力计算中的一个重要动力参数———附加水质量的计算方法进行了模型实验研究,提出了通过动力模型实验确定附加水质量的方法。依据结构动力学理论,由无水情况和各种不同水深情况下沉箱动力特性的实验数据确定沉箱运动时的附加水质量;在对实验结果进行统计分析的基础上,建立了计算附加水质量的经验计算公式。最后通过数值模拟与实验结果的比较,对建立的经验公式进行了检验。A model experimental study on the calculation method of hydrodynamic mass, which is an important dynamic parameter in dynamic calculation of caisson breakwater, is conducted. The procedure determining the hydrodynamic mass of caisson is presented. According to the dynamic theory of structures, the hydrodynamic mass is determined by the dynamic behaviors of caisson measured in the model experiment under the conditions of no water and various water depths. On the basis of the experimental results, an approximate formula for calculating hydrodynamic mass is proposed. Finally, the approximate formula is tested through comparison between the dynamic responses calculated by numerical model and those measured in the model experiment.
