The influence mechanism compressed air half-closed in bucket to the float state of structure is analyzed, and an analysis method to calculate the float state of structure with air-filled buckets is established. The formula to calculate the flotage of air-filled bucket and the force equilibrium equations of structure are derived according to the assumption that the compression relationship of the air half-closed in bucket is linear. The following analysis methods about the property parameters of air-float structure are obtained. The comparisons of theory and model test and local test show that the float state analysis method about air-float structures can be applied to engineering. It is possible that the transportation and installation of some large bucket foundation structures in coastal and offshore engineering can be went on by the reasonably using of properties of air-float.
