Performance of Buried Pipes with Flowable Fill and Granular Stone as Backfill Materials

Flowable mixtures and granular stone materials are frequently used as backfill materials for buried pipes. The objectives of this research are to perform an investigation on the performance of double-walled buried flexible pipes using flowable materials and granular stone as backfills. HDPE, PVC, concrete, and metal pipes ranging in diameter from 12 to 108 inches will be considered. Additionally, the influence of trench width on the performance of single-wall and double-walled buried pipes under different burial conditions will be investigated. A numerical model based on the Finite Element Method will be the primary basis for the investigation.
