Abstract
The 2024 Noto Peninsula earthquake caused various earthquake damages to water-supply
pipelines. This paper reports the results of our field survey of earthquake damage to water pipe
bridges. The damage to the water pipe bridges was caused by the displacement of the ground
behind the abutments or between the abutments during the earthquake, but not by the inertia
force of pipes. Damage modes of the abutments can be classified into settlement of the ground
behind the abutments, tilt of the abutments, and horizontal movement of the abutments. The
abutment displacement caused various damages to the pipelines of the water pipe bridges.
