A method of analysis for buried arches with footings was developed to predict their response to a nuclear airblast overpressure. The method of analysis was formulated by considering the arch ring as a discrete model consisting of a finite number of nodes (flexible joints) connected by rigid bars initially of equal length. The results of laboratory and field tests on 1/4.5- and 1/2-scale models, respectively, of an arch structure are compared with predictions made using the analysis. Arch internal loads, footing motions, and free-field motions are compared with those predicted by the analysis and compare favorably. The analytical technique was used to predict the response of the prototype structure to a 140-psi air overpressure loading resulting from the detonation of 10-kt, 100-kt, and 1-Mt weapons, to a 100-psi air overpressure for a 1-Mt weapon, and to the Operation Prairie Flat (500-ton TNT) 140-psi overpressure and the predicted response was compared with that assumed in designing the structure. The method of analysis developed is recommended whenever a significant cost savings can be realized because a number of structures are to be constructed or when local soil conditions make design by cruder methods uncertain.

It was evident that the passive pressures which developed on the sides played the dominant role in providing resistance. It has been found that in static tests some of the surface load is carried by arching through the soil. In the dynamic tests the inertial forces of the soil above the arch were found to be important. The inertial load overcame the soil shear resistance so that a load approximately equal to the surface load acted on the structure. A model analysis of the system and subsequent comparison of the deflections from the small-structure tests and the Operation Plumbbob Structure 3.3 tests indicate that modeling of deflections is possible.

Rock Dynamics: Progress and Prospect contains 153 scientific and technical papers presented at the Fourth International Conference on Rock Dynamics and Applications (RocDyn-4, Xuzhou, China, 17-19 August 2022). The two-volume set has 7 sections. Volume 1 includes the first four sections with 6 keynotes and 5 young scholar plenary session papers, and contributions on analysis and theoretical development, and experimental testing and techniques. Volume 2 contains the remaining three sections with 74 papers on numerical modelling and methods, seismic and earthquake engineering, and rock excavation and engineering. Rock Dynamics: Progress and Prospect will serve as a reference on developments in rock dynamics scientific research and on rock dynamics engineering applications. The previous volumes in this series (RocDyn-1, RocDyn-2, and RocDyn-3) are also available via CRC Press.

The objective of the study was to investigate and verify model-to-prototype scaling relations for blast loaded buried arches that respond both elastically and inelastically. Four geometrically similar, semicircular aluminum alloy arches with 4-, 8-, 12-, and 36-inch diameters were buried in dense dry sand and subjected to air-blast-induced loads on the surface. The tests were conducted at the Large Blast Load Generator located at the U.S. Army Engineer Waterways Experiment Station. The results of two series of tests, each consisting of 3 repeated shots, ranging from 70 to 300 psi, are presented. Within the range of parameters investigated, the scaling of the dependent variables were adequately verified. These variables included acceleration, velocity, displacement, thrust, and bending moment. (Author).
