This research was performed to obtain information on the behavior of shallow-buried cylinders subjected to static and blast loads in support of the task objective of gaining knowledge to provide guidelines for developing design methods for underground protective structures. It was especially desired to obtain data on the time and space variations of deflection, thrust, and moment under the two types of loading for purposes of making a comparison. The results show that the net arching across a flexible shallow-buried cylinder is small and that the maximum moment occurs at the bottom of the cylinder. Differences in response to static and blast loading are relatively small except for the crown, which deflects about twice as much under blast loading as under corresponding static loading. An analogy with the simple spring-mass system is drawn to explain this behavior. Information obtained on the influence of placing a low- strength isolating material in the soil over a cylinder indicates that such an expedient is of questionable benefit.

The general objective of the investigation was to study experimentally the behavior to failure of flexible, horizontally oriented cylinders buried at various depths in dense, dry sand and subjected to either static or dynamic surface overpressures. Static and dynamic tests were conducted on 33 different cylinders, fabricated of high-yield-strength aluminum. Results indicated that collapse of the cylinders occurred while the strains in the cylinder walls were still in the elastic range. The cylinders buried at the shallow depths (zero to one-half cylinder diameter above the crown) collapsed by a catastrophic snap-through or caving of the crown. For the cylinders buried at depths of three-quarters to two cylinder diameters above the crown, the mode of collapse was an instantaneous elastic buckle that occurred at the spring line or invert of the cylinder. The collapse mode of the cylinders under dynamic overpressure was similar to that of the cylinders collapsing under static overpressure. The results of the investigation verified the applicability of an equation for predicting the static collapse overpressure for smooth-walled, horizontally oriented, buried cylindrical structures and entranceways. The hoop-compression theory was found to be applicable for analyzing the structural design to determine if the cylinder would collapse in the elastic range. (Author).
