noun
abutment
Rare technical term in civil engineering or architecture referring to the supporting structure at the ends of a bridge or arch.
橋梁の設計では、迫り台の強度が重要です。
In bridge design, the strength of the abutment is important.
橋台 is the standard modern term for a bridge abutment; 迫り台 is a rare synonym used in specific technical contexts.
Compound of 迫り (seri, 'thrusting' or 'pressing') and 台 (dai, 'platform' or 'base'), likely referring to the structural support that bears the thrust of an arch or bridge. The exact historical derivation is uncertain.
