Abstract : Ground motion data are presented from Project DIP IIIA, the third experiment in the DIHEST Improvement Program (DIP) Series. The experiment, fired 20 May 1972 near Albuquerque, New Mexico, was designed to measure velocity, acceleration, displacement, soil stress, and blast pressure from the detonation of a 6600-pound buried, decoupled Direct-Induced High-Explosive Simulation Technique (DIHEST) array of slurry explosive. Rear boundary relief was provided on the east side of the array in the form of a long deep trench situated 100 feet away and parallel to the explosive array. On the west side of the array the boundary relief consisted of two rows of deep 4-foot diameter holes. The free-field ground motion instruments were installed 5 to 60 feet deep in 12-inch diameter holes in a rectilinear array at distances of 16 to 90 feet from the plane of the explosive array. Plots of the electronic data traces are presented. The response of four buried cylindrical research structures to the explosion is also reported. (Author)
