Development of Engineering Criteria for Use of Slurry-Type Explosives Against Tactical Structural Targets.

摘要

The objective of this study was to determine the effectiveness of a slurry-type explosive against common construction materials and to investigate the operational aspect of employing slurry against structural targets. The investigation of slurry as a demolition charge was divided into two test phases. The first phase was conducted on structural elements. A total of 54 tests were conducted: 11 tests of steel plates 1/2, 1/4, 3/8, and 1 inch thick; 27 tests of wide-flange steel beams; 11 tests of 12- and 16-inch-square reinforced concrete piers; and 5 tests of 12-inch-square wood (green oak) members. The second phase consisted of four prototype bridges: two wide-flange steel stringer types, 40-foot clear spans; one reinforced concrete, 40-foot clear span; and one steel truss, 108-foot clear span. Slurry was demonstrated to be effective against structural elements and prototype bridge structures. Recommendations for the use of slurries are presented. (Author)
