Available in PDF, EPUB and Kindle. Book excerpt: A review of ground shock data from recent large, near-surface high-explosive tests is made. Emphasis is on close-in motions in rock. Wave forms are shown for selected shots and locations. Comparisons are made among wave forms for similar test conditions in different geologic materials including soil, shale, granite, and sandstone. Variations in peak motion amplitudes at various depths and ranges are discussed for the different geologic materials. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Small-scale laboratory experiments were conducted and analyzed to study the effect of the proximity of the free surface on the seismic ground motions. Two classes of experiments were done. In one the charges were far from the free-surface and the free-field displacement-time histories were measured. In the second class the charges were near the surface and were either fully contained or formed a crater. The charges were 0.25 g of PETN in concrete cylinders, 120 cm in diameter and 33 to 60 cm thick. In all experiments displacements were measured 30.5 cm directly below the charges. The experiments produced consistent and repeatable data. A striking feature of the ground motions for the near surface experiments is a large long-period negative pulse which is present whether or not cratering occured. The results were studied by comparing to numerical simulations of the experiments using a Lagrangian finite difference program and published properties of the concrete and PETN. The calculations are in good agreement with the laboratory data, providing verification of both the constitutive models and the methods.

This book was released on 1973 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Outrunning ground shock data from the 100- to 10-psi overpressure decade in six large surface high explosive (HE) tests, three from a rock site and three from a glaciated soil site, were analyzed for the effect of gross changes in constitutive properties. Axisymmetric wave propagation code calculations in layered linear and nonlinear (incrementally elastic-plastic) media were performed to determine the effects of introducing nonlinearity, selected material property variations, and the relative importance of airblast and direct induced effects from surface explosions in the overpressure decade of interest.
