摘要：	A multi-plate corrugated steel culvert was built on Nease Creek in southeast Ohio under SR 224 and US33. The culvert was 252 inches in diameter and 439 feet long. The culvert was covered with up to 75 feet of backfill consisting of ODOT No. 304 crushed limestone and local silty clay soil. The steel plates were 0.375 inches thick and had a 6 inch by 2 inch corrugation profile. The culvert design used slotted blot joints to relieve stress caused by backfill. Earth pressure cells were mounted around the culvert to measure vertical soil pressure at the crown and at the springline and horizontal soil pressure at the springline underneathteh centerline and shoulder of the road. The horizontal and vertical diameters of the culvert were measured during and after construction. CANDE-89 was used to generate a finite element model of the culvert during and after construction.
