PROBLEM TO BE SOLVED: To provide a construction method for a vibration cutoff structure capable of reducing vibrations transmitted to vibration reception-side ground from excitation-side ground, while reducing construction costs.SOLUTION: A construction method for a vibration cutoff structure includes: a ditch excavation step of forming a ditch 14 by excavating natural ground between excitation-side ground 10 and vibration reception-side ground 12; a vibration cutoff material installation step of installing bubble buffer sheets 20 and 22 lower in density than the natural ground along a side wall 14C, on the side of the vibration reception-side ground 12, of the ditch 14 from the ground; and a back-filling step of back-filling the ditch 14. |
