主　　题：tetrapod bucket foundation response amplitude operator(RAO) draft water depth spacing air-floating 

摘      要：Air floating transport is one of the key construction technologies of bucket *** influences of draft,water depth and bucket spacing on the motion response characteristics of tetrapod bucket foundation(TBF)during air-floating transportation were studied by models *** results showed that with the increase of draft,the natural periods of heave motion increased,while the maximum amplitudes of oscillating motion *** maximum amplitudes of heave motion decreased while pitch motion increased with the increasing of water depth;further,the period range of oscillating amplitude close to the maximum amplitude was expanded due to shallow water *** increasing bucket spacing,the maximum amplitudes of heave motion first increase and then decreased,whereas the maximum amplitudes of pitch motion ***,the favorable air-floating transportation performance can be achieved by choosing a larger bucket spacing under the condition of meeting the design requirements and reducing the draft under shallower water.
