Abstract:
FROM BURMISTER'S THEORY OF STRESS IN ELASTIC, LAYERED SYSTEMS, EQUATIONS FOR STRESS ARE DEVELOPED FOR A POINT AT THE FIRST INTERFACE ON THE AXIS OF A CIRCULAR LOADED AREA. NUMERICAL RESULTS ARE GIVEN FOR VARIOUS DEGREES OF RELATIVE STIFFNESS OF THE LAYERS COMPRISING TWO- AND THREE-LAYERED SYSTEMS. THE CASE OF THE FRICTIONLESS INTERFACE IN TWO- LAYERED SYSTEMS, AND THE CASE OF PERFECT CONTINUITY AT THE INTERFACE IN SOME TYPICAL TWO- AND THREE-LAYERED SYTEMS, ARE TREATED. LABORATORY MEASURED STRENGTHS OF THREE SOIL-CEMENT MIXES AND TWO FLEXIBLE BASE MATERIALS ARE COMPARED WITH STRESS COMPUTED FROM THE TWO-LAYER THEORY FOR A TYPICAL CONDITION OF LOADING, AND THE CORRESPONDING REQUIRED DEPTHS OF BASE ARE ARRIVED AT BY A GRAPHICAL METHOD BASED ON THE USE OF THE MOHR'S RUPTURE ENVELOPE. THE THREE-LAYER THEORY IS EMPLOYED TO STUDY THE EFFECT OF THIN SUB-BASES UNDER CONCRETE SLABS. /AUTHOR/
