应用边界积分方程方法研究了波浪与2个相连三维浮体的相互作用问题。计算中考虑了浮体相互间的水动力干涉，通过联立各浮体的运动方程以及运动连续条件求得浮体运动量。计算了2个铰连接漂浮方箱组成的系统，同Newman的结果进行了对比,当入射波的频率不在系统的自振频率附近时，结果与Newman的结果吻合良好，在自振频率附近时，铰接点处的转角和垂向位移都发生快速变化，而Newman未提到这一现象。

In this paper, boundary integral equation method is used to study the hydrodynamic interaction effects between wave and two connected floating structures. The hydrodynamic interaction between the two bodies is considered. The amplitudes of the body motions are determined according to the motion equations of the two bodies and the continuous conditions at the connection between the bodies. In order to verify this method, the heave amplitude at the hinged joint and the relative angular deflection of two floating barges, which connected by a hinge, are calculated and compared with the results from Newman. The comparison shows that the present calculation agrees well with Newman's result except at the nearby of the resonant frequency of the system. At the resonant frequency of the hinged system the present result changes quickly, but Newman did not mention the phenomenon.
