In civil engineering, a cutting or cut is where part of a hill or mountain is cut out to make way for a road or rail line. It is in cut and fill construction used to keep the route straight and/or flat, where the comparative cost or practicality of alternate solutions (such as diversion) is too prohibitive. Contrary to the general meaning of cutting, a cutting in construction is mechanically excavated or blasted out with carefully-placed explosives.

  • In civil engineering, a cutting or cut is where part of a hill or mountain is cut out to make way for a road or rail line. It is in cut and fill construction used to keep the route straight and/or flat, where the comparative cost or practicality of alternate solutions (such as diversion) is too prohibitive. Contrary to the general meaning of cutting, a cutting in construction is mechanically excavated or blasted out with carefully-placed explosives. The cutting may only be on one side of a slope, or directly through the middle or top of a hill. Generally, a cutting is open at the top (otherwise it is a tunnel). A cutting is (in a sense) the opposite of an embankment. The word is also used in the same sense in mining, as in open cut mine.
  • 切土（きりど）とは、高い地盤・斜面を切り取って低くし、平坦な地表を作る、あるいは周囲より低くする工事。また、その工事で切り取った土砂のこと。山間部の工事では切土部分と盛土部分の体積を近づけ、切土を盛土に用いることで建設コストを安くできる。 連続的な切土により周囲の土地より低くして鉄道や道路を通した部分は堀割（ほりわり）という。 ファイル:Kuji Tsudayama 06a2345as. jpg 国道246号線の切土部分 京王高尾線めじろ台駅付近の掘割 ファイル:North end of Farringdon station. jpg 堀割に作られたロンドン地下鉄（左）およびネットワーク・レールの線路（都心部のファリンドン駅付近）
