英文摘要：
The research on the very large floating structures is becoming a hot issue in the worldwide ocean engineering field,and how to analyze the hydroelastic responses of the very large floating structures in waves is a key factor in the process of design. The very large floating structure was considered as a ＂ two dimensional＂ thick plate and the wave linear potential theory was employed. By combining the eigenfunction expansion method and the mode function expansion method,hydroelastic responses,such as displacement and bending moments distribution of the structure can be obtained with a few computations. The influences of different environmental factors on the hydroelastic response of the very large floating structure are also analyzed. A comparison is made between the experimental results and the results of different mode functions. This research is a complement to the study on very large floating structures.
