摘　　要：对带底圈重力式网箱在纯波浪作用下的锚绳受力进行了研究,获得了锚绳受力峰值及相位关系的基本规律。给出了这一形式下的锚绳受力经验公式,为网箱设计、选型提供参考。研究成果将有利于更深入地了解重力式网箱的水动力特性。The force mechanics of the wave and current acting on the Gravity Cage is rather complicated since the Gravity Cage is a kind of flexible floating structures. It is difficult to get knowledge only by theoretical ways. Physical model tests are still the important means for such kind of studies. The hydrodynamic behaviors of the Gravity Cage has the relationship with many factors such as cage style, style and mass of the weighting system, mooring style and method for submergence of cage, etc. This paper focuses on the analysis of the mooring line forces and the phase of its appearance of Gravity Cage with bottom ring in wave only conditions. Results of this study will give useful references for better knowledge of hydrodynamic behavior of Gravity Cage and give guides for cage design and open ocean aquaculture.
