The flow field of rectangular floating body near submerged breakwater was calculated and analyzed by using eigenfunction expansion and border matching method to derive the fluid force of floating body. The variation of hydrodynamic force under different admission frequency was obtained by changing the distance between floating body and submerged breakwater as well as submerged height. The superposition of transmitted wave and reflected wave in the water area between floating body and submerged breakwater caused free-face radical change. In same time, the hydrodynamic force acting on the floating body produces oscillations at resonant frequency. The comparative analysis shows that the proposed calculation model can be used in hydrodynamic analysis of floating body near submerger breakwater.
