The ojbective of this project is to investigate the interaction effects of directionality of waves and combined environmental conditions, such as, wind, wave and current.The following seven topics have been investigated for three year's since 1986.1) Review of the researches on the behavior of a floating body under combined environmental wind, wave and current forces.2) Generation, measurement and analysis of multi directional weves in a model basin.3) Behavior of a floating body and a riser in multi-directional waves.4) Hydrodynamic forces on a floating body in combined wind and current.5) Hydrodynamic forces on a floating body in combined wind and wave.6) Hydrodynamic forces on a floating body in combined wave and current.7) Numerical calculation of separated flow around a cylinder in current.

该项目的目的是研究波浪方向性与风、浪、流等综合环境条件的相互作用效应。自1986年以来，历时三年对以下七个课题进行了研究。1）浮体在风、浪、流综合力作用下的行为研究综述。2）模型盆地中多向波浪的生成、测量和分析。3）浮体和立管在模型盆地中的行为。 4）风浪组合作用下浮体的水动力。5）风浪组合作用下浮体的水动力。6）波流组合作用下浮体的水动力。7）水流中圆柱体周围分离流的数值计算。
