ENGINEERING PROPERTIES OF NUCLEAR CRATERS. THEORETICAL STUDIES OF CRATERING MECHANISMS AFFECTING THE STABILITY OF CRATERED SLOPES.

CRATERING PHENOMENON WERE STUDIED IN THREE SPECIFIC SITUATIONS OF PARTICULAR INTEREST IN ENGINEERING PRACTICE, NAMELY: (1) WHERE THE CRATERED MEDIUM IS SUBMERGED UNDER THE THE WATER TABLE, (2) WHERE THE SURFACE OF THE CRATERED MEDIUM IS SLOPED, AND (3) WHERE SEVERAL EXPLOSIVE CHARGES ARE SET OFF SIMULTANEOUSLY IN A MEDIUM. A SUCCESSFUL ATTEMPT WAS MADE TO MEASURE THE PORE-FLUID STRESS WAVES CAUSED BY AN EXPLOSION IN MEDIA SUCH AS SUBMERGED, DENSE SAND AND VERY SOFT, BENTONITE CLAY. SIMPLE, DIMENSIONAL EXPRESSIONS WERE FOUND FOR THE PEAK POSITIVE STRESS OF THE FLUID-WAVE IN SAND. THIS STRESS APPEARS TO BE PROPORTIONAL TO THE ENERGY YIELD OF THE CHARGE AND TO DECAY IN INVERSE PROPORTION TO THE CUBE OF DISTANCE FROM THE EXPLOSIVE CHARGE. RESIDUAL PORE-FLUID STRESSES FOLLOWING AN EXPLOSION APPEAR TO BE ASSOCIATED WITH STRUCTURAL CHANGES IN THE CRATERED MEDIUM. TESTS WITH MULTIPLE CHARGES SHOWED A SEQUENCE OF EVENTS WHICH BEAR SOME SIMILARITY WITH CRATERING PHENOMENON IN THE CASE OF SINGLE CHARGES.
