The general objective of this investigation was to study experimentally the behavior to failure of flexible, horizontally oriented circular tubes buried at various depths in dense, dry sand and subjected to dynamic surface overpressures. Dynamic tests were conducted on ten brass tubes in the Small Blast Load Generator. The tubes had a wall thickness of 0.005 inch, an outside diameter of 4 inches, and a specially isolated 5.75-inch-long test section. The tubes were flexible and had a stiffness EI/R3 of 0.018 psi. To examine the effect of depth of burial, tests were conducted in dense, dry sand at depths ranging from 1 to 16 inches, or four tube diameters above the crown. The dynamic tests were conducted at overpressures ranging from 6.2 to 34.9 psi. Measurements were made of the applied overpressure, and the tube deflection was recorded by means of a high-speed camera linked to the pressure-time base. Results indicate that collapse of the tubes was initiated by a buckle that occurred along a longitudinal seam where the tubes were spliced. The dynamic collapse overpressure increased greatly with increased depth of burial down to a depth of one tube diameter; subsequently, the increase in collapse overpressure with increase of burial depth to four tube diameters was insignificant. The dynamic collapse overpressure was approximately the same as the static collapse overpressure as determined from correlation with previously reported results. The results of this investigation have verified the applicability of an equation for predicting the dynamic collapse overpressure of very flexible tubes. (Author).

Much of the infrastructure of modern society is buried below ground. Pipeline, conduits and culverts carry the services on which our economies depend and the strength and resilience of such structures is of vital importance. Larger underground construction is becoming more common in cities and towns, and in defence installations. This book brings together the store of theoretical, analytical, experimental and design-based knowledge that has been built up on the subject of buried structures. The author discusses the principles of soil arching, stress distribution and soil properties, as well as the design problems of static and dynamic loads, strength and safety. The stability of thin-walled buried structures receives particular attention, as does the behaviour of underground construction under localized and nuclear explosions. Test facilities and design codes of practice are reviewed, and the range of structures discussed in the book extends from thick- and thin-walled culverts, conduits and water pipelines to arches, domes, spherical shells, vertical capsules, blast shelters and thin-walled road tunnels.
