| 摘 要： | 为了研究不同水深下筒型基础拖航中的运动响应，以海军某筒型基础平台为研究对象，在拖航干舷、筒的位置以及波浪条件一定的前提下，通过模型试验测定筒型基础平台在不同水深下随浪和顶浪拖航时在横荡、纵荡和垂荡方向上的加速度、筒内气压力和筒底水压力以及拖航中的拖缆力．试验结果表明，在筒型基础由浅水进入深水拖航的过程中，平台的稳定性能和操纵性能下降，且出现倾覆现象，必须降低船速和设置护航船防止漂移，且15m水深时该平台的航速不能超过1．5节（0．771m／s），20m水深时航速不能超过1．0节（0．514m／s）．

| Abstract: | In order to study the response of bucket foundation in towing with different water depth,a model test was made to measure the acceleration of swaying,surging and heaving,the internal air pressure and bottom water pres-sure of the bucket and the towing power of platform,under the same conditions of draught,location of buckets and incident wave,taking a naval bucket foundation platform as an example.It is shown that in the towing of bucket foundation from shallow water to deep water,the stability and maneuverability of the platform degrade quickly and the overturning phenomenon occurs in deep water.In order to solve these problems,the speed of towing must be re-duced and escort vessels must be set to avoid swinging.When the water depth is 15 m and 20 m,the speed of towing must be less than 1.5 knots(0.771 m/s)and 1.0 knot(0.514 m/s),respectively. |
