摘　　要：通过不规则波物理模型试验,在前人对开孔沉箱波浪力研究的基础上进一步研究了透空式上部结构开孔沉箱前沿的波浪力。分析了结构前沿的波压力分布规律并与现有的波压力计算公式进行对比,发现透空式上部结构面板和底部沉箱结构前沿波压力的计算可通过合田良实公式进行修正,而上部结构纵梁所受的相对点压强值往往较大,因此单独对纵梁上的相对波压强进行分析,给出了计算相对波压强值的经验公式。Based on the previous research on wave forces of perforated caisson, we further study wave forces at the forefront of the perforated caisson with permeable superstructure through physical model tests of irregular waves. Analyzing the regular pattern of pressure distribution and comparing it with the existing formula of wave pressure, we find that the formula can be modified based on the Aida Yoshizane formula which is applied to the calculation of the pressure distribution of the upper structure＇s panel and the forefront of the lower part of perforated caisson with permeable superstructure. The stringers of the upper structure suffer greater relative point pressure. So, the relative wave pressure of stringers is studied separately and the empirical formula for calculating relative wave pressure is provided here.
