Induced trench method
Webmethod (sometimes called the induced trench method) of construction. Penman et al. (2) measured the earth pressure on a rigid reinforced concrete culvert below 53 m of rockfill. The mea sured vertical earth pressure on the culvert crown was about two times the overburden. Hoeg (3) performed model tests http://conf.tac-atc.ca/english/resourcecentre/readingroom/conference/conf2007/docs/s19/hansen2.pdf#:~:text=The%20induced%20trench%20method%20of%20culvert%20construction%20has,Marston%20and%20Sprangler%20in%20the%202420%E2%80%99s%20and%202430%E2%80%99s.
