Blasting Vibrations and Their Effects on Structures

Description: Report issued by the Bureau of Mines over the effects of air blast vibrations. As stated in the abstract, "this report presents the results of the Bureau of Mines 10-year program to study the problem of air blast and ground vibrations generated by blasting" (p. 1). This report includes tables, and illustrations.

Preshot and Postshot Safety Survey of Oil and Gas Facilities, Baxterville Field, Mississippi, Final Report

Description: From introduction: Oil and gas wells and related facilities of the Baxterville field were surveyed to document any physical changes resulting from the Salmon Event. All such structures within a 5-mile radius of Ground Zero were examined and photographed in detail.

Craters From Four Equal Charges in a Horizontal Square Array

Description: Craters were observed resulting from square arrays of 64-pound charges at various spacings and depths. The closest spacings yielded craters very like those from single 256-pound charges, while wider spacings yielded craters more or less square in shape and with a mound or pier at the center. Generally, the areas so uncovered were greater than for single 256-pound charges, except for very deep charges. Volumes, too, were enhanced by this configuration by as much as a factor of three. If the same… more

Curves for Estimating Low Blast Over-Pressure

Description: A plot of overpressure versus distance is presented for the fractional psi pressure level. The plot provides a rapid and simple means of estimating the permissible yield at any distance from settled areas.

Response of Deep Two-Way-Reinforced and Unreinforced Concrete Slabs to Static and Dynamic Loading, Report 3: Static Tests of Deep Slabs Having a Span-to-Thickness Ratio of 4.12

Description: Partial abstract: "The objective of the investigation reported herein was to obtain laboratory response data for deep, two-way-reinforced and plain concrete slabs subjected to static overpressures in order to determine the response analysis necessary to analyze the target vulnerability of such structures under both active and passive defense situations" (p. 4).

Effect of Backfill Property and Airblast Variations on the External Loads Delivered to Buried Box Structures

Description: Partial abstract: "The results of analytical studies are presented in which (i) the SAP IV elastic finite-element (FE) code was used to perform modal analyses for a rectangular structure in vacuo and embedded in different backfill materials, and (2) a series of dynamic and static two-dimensional (2D), plane-strain, FE, structure-medium interaction (SMI) code calculations were performed using the HONDO code."

Close-in Air Blast from a Row Charge in Basalt

Description: From abstract: Close-in air blast measurements were made on the Dugout shot. Major constituents of the blast wave were the ground-shock-induced pulse and the pulse from venting gases. The ground-shock-induced pulse was the dominant one at all stations.
