The invention discloses an air bag filling type truss for a large ocean platform. Air bag supporting frames are used for replacing transverse diagonal web members in space trusses, and then air bag filling is performed, so that the air bag filling type truss is formed. The air bag filling type truss is composed of longitudinal chord members, transverse chord members, vertical web members, longitudinal diagonal web members, the transverse air bag supporting frames and an air bag. The air bag supporting frames are connected with the reserved fixing ends of the truss through reserved connectors via bolts. After the air bag is filled with air, the whole air bag filling type truss can bear external loads and also can provide buoyancy in water. A lot of air bag filling type trusses and the space three-dimensional trusses are connected according to a certain rule so that the large ocean platform structure can be formed. The air bag filling type truss maintains the advantages that the air bag structure is light and good in buoyancy performance, and the space trusses are convenient and rapid to construct and high in rigidity, and forms a floating structure system which is light, high in strength, convenient to construct, convenient and rapid to expand and capable of achieving partial balance between internal air pressure of the air bag and external water pressure.
