Experimental Investigation of the Performance of Buried Flexible Pipe in Reinforced Sand

Abstract The experimental work of this study deals with the performance pipe in sand various responses subjected to incremental static loading where backfill is reinforced two types reinforcement (geogrid and geocell) investigate effects cover. pipes considered are installed different densities; i.e., loose, medium dense sand, a constant burial depth (2D, D diameter). It was concluded that maximum deformation occurs at crown pipe. increases when density decreases. For equal 1.5 D, strain on by about 22.5% changes from 36.8% it loose. vertical stress above buried loose reduced 8.3% geogrid width 2B B footing width, while 22% B. When geocell used, percent reduction 62%. 28% 40% 68% used.
