To provide a passing wave damping structure for a fixed construction, which damps pressure waves with a low frequency in open zones other than a tunnel zone.

A passing wave damping section 5 functions to dampen construction passing waves generated when a train 1 moving in the open zones passes in the vicinity of the fixed construction 3. If no passing wave damping section 5 is provided for the fixed construction 3, when the train 1 passes the fixed construction 3 at a high speed, the train 1 and the fixed construction 3 interfere with each other to generate pulsed construction passing waves. If the passing wave damping section 5 is provided for the fixed construction 3, when the train 1 approaches the fixed construction 3 at a high traveling speed on a railway 2, a front vehicle 1a progressively overlaps the passing wave damping section 5 and then passes under the fixed construction 3 when viewed from a location C. Therefore generation of the construction passing waves due to interference between the train 1 and the fixed construction 3 is damped by the passing wave damping section 5.
