PROBLEM TO BE SOLVED: To provide a vibration isolation banking structure which is constructed in a single procedure of civil engineering works in a manner taking both vibration cut-off countermeasures and aseismic countermeasure, and imposes only a small social burden in terms of a lot, costs, and a construction period, and to provide a method of constructing the vibration isolation banking structure. SOLUTION: The banking structure is formed of steel wall members 1, 3 each having a lower end set in the ground 2 and a ground portion functioning as a form, vibration cut-off members 5 each arranged along an underground portion of the steel wall member 1 or 3, and mixed soil 7 placed inside the steel wall members 1, 3. Each vibration cut-off member 5 is comprised of a wall member 11 or 13 which is opposed to the steel wall member 1 or 3 and spaced at a predetermined interval away from the same, and vibration isolation materials 15 arranged between the wall member 11 or 13 and the steel wall member 1 or 3. In the vibration isolation material 15, the rigidity thereof in the direction of a steel wall member surface is smaller than the rigidity in a direction at a right angle to the steel wall member surface.
