Full-scale testing of buried extensible pipes subject to axial soil loading

With this background, a series of full-scale laboratory pipe pullout tests were performed at the University of British Columbia (in collaboration with Terasen Gas, Vancouver, Canada) with the intention of advancing the knowledge base for buried extensible pipe. This paper presents details related to this experimental work along with analytical framework for derivation of axial soil-springs that formed the basis for a numerical analysis of the pullout tests.
