STRESS AROUND PRESSURIZED SPHERICAL CAVITIES IN TRIAXIAL STRESS FIELDS

THE STRESS AT A GIVEN POINT AROUND A PRESSURIZED SPHERICAL CAVITY IN AN APPLIED TRIAXIAL STRESS FIELD CAN BE CALCULATED USING THE EQUATIONS PRESENTED IN THIS ARTICLE. THE SPHERICAL CAVITY IS ASSUMED TO BE BURIED AT A DEPTH OF GREATER THAN 6 CAVITY RADII AND THE APPLIED TRIAXIAL STRESS FIELD IS ASSUMED TO BE CONSTANT. VECTOR AND DYADIC TRANSFORMATION EQUATIONS AND THE PRINCIPLE OF SUPER-POSITION ARE USED TO INSURE THAT THE STRESS COMPONENTS CAUSED BY EACH SOURCE OF INFLUENCE ARE (1) CALCULATED AT A COMMON POINT OF INTEREST, AND (2) DIRECTIONALLY COINCIDENTAL AT THAT POINT. THE EQUATIONS HAVE BEEN CODED AND USED TO CALCULATE (1) THE SIX INDEPENDENT COMPONENTS OF STRESS AT A POINT, (2) THE MAGNITUDE AND DIRECTION OF PRINCIPAL STRESSES AT A POINT, AND (3) THE STRESS COMPONENT NORMAL TO A PLANE OF INTEREST INTERSECTING THE CAVITY. THE EQUATIONS CAN BE USED TO CALCULATE STRESS FOR A WIDE VARIETY OF UNDERGROUND SPHERICAL CAVITIES SUCH AS UNDERGROUND GAS-STORAGE CAVITIES AND MAGMA CHAMBERS. /AUTHOR/
