摘　　要：超大型浮体(VeryLargeFloatingStructure,VLFS)作为人类开发海洋的前沿基地,正在成为世界各国海洋工程界研究的一个热点。由于超大型浮体覆盖的面积比普通的船舶和海洋结构物要大很多,其首尾两端所处的海洋环境可能有显著的差异,因此必须考虑非均匀海洋环境对其水弹性性能的影响。介绍了国内首次进行的箱式超大型浮体在非均匀海洋环境中的水弹性试验,对非均匀海洋环境、超大型浮体的水弹性性能以及两者相互之间的关系进行了研究。Very Large Floating Structure (VLFS) has been paid more and more attention in exploitation of ocean resources. The hull of VLFS covers much more sea area than ships and conventional floating structures. It is important to consider the effect of non-uniform sea environment on VLFS. In this paper, the model tests of the hydroelastic response of box-typed VLFS in non-uniform sea environment are presented. The tests were performed to investigate the distribution of wave height around elliptic shoals, and the characteristics of motion and deformation of VLFS in non-uniform sea environment.
