Provided is a suction pile including a support means which is interpenetrated into the ground on the outside surface of the suction pile and is formed to increase contact surface with the ground and added mass to maximize bearing power into the ground due to increase of not only contact surface with the ground while interpenetrated into the sea bottom but added mass. Accordingly, high fixation power can be maintained and excellent safety can be secured when connecting the suction pile with a mooring line of a sea structure.
