Description/Abstract:
PROJECT 1.3 ATTEMPTED TO MEASURE DYNAMIC STRESS AND STRAIN INDUCED IN THE EARTH BY THE PASSAGE OF AN AIRLBAST WAVE OVER THE SURFACE WITH THE AID OF A NEWLY DEVELOPED STRESS GAGE. AN ARRAY OF OMNIDIRECTIONAL VEL OCITY-SENSITIVE SWITCHES WAS ALSO INCLUDED IN A ATTEMPT TO DISTINGUISH BETWEEN, AND MEASURE, THE PROPAGATION VELOCITIES OF THE PEAK COMPRESS ION AND SHEAR STRESS FRONTS INDUCED BY THE AIRBLAST IN THE EARTH. DUE TO RADIATION EFFECTS PRODUCED BY THE DETONATION, THE STRESS GAGES FAI LED TO GIVE ANY USABLE STRESS OR STRAIN DATA. THE TIME-OF-ARRIVAL SWI TCH ARRAY PERFORMED SATISFACTORILY, AND COMPRESSIONAL WAVE VELOCITY DA TA IS PRESENTED TOGETHER WITH CALCULATIONS OF CONSTRAINED MODULUS FOR FRENCHMAN FLAT SOIL. FLEXIBLE CASING WAS ALSO INSTALLED AT SEVERAL RA NGES CLOSE TO GROUND ZERO FOR MEASUREMENT OF PERMANENT GROUND DEFORMAT ION. DATA ON PERMANENT HORIZONTAL AND VERTICAL MOVEMENT WITH DEPTH IS PRESENTED.
