Title:

INFLUENCE CHARTS FOR TWO-LAYER ELASTIC FOUNDATIONS

Abstract:

INFLUENCE CHARTS DEVELOPED BY NEWMARK HAVE BEEN USED QUITE EXTENSIVELY FOR COMPUTING STRESSES IN SOIL FOUNDA- TIONS. THE CHARTS ARE BASED ON BOUSSINESQ'S THEORY BY ASSUMING THAT THE SOIL IS SEMI-INFINITE, HOMOGENEOUS, ISOTROPIC, AND ELASTIC. THIS TECHNICAL NOTE PRESENTS INFLUENCE CHARTS WHICH ARE SIMILAR TO AND ARE USED IN THE SAME MANNER AS THOSE PRESENTED BY NEWMARK FOR COMPUTING THE VERTICAL STRESSES AT THE INTERFACE OF THE TWO LAYERS AND THE VERTICAL DEFLECTIONS ON THE SURFACE OF A TWO-LAYER FOUNDATION. THE DESIGN OF THESE TWO-LAYER FOUNDATIONS GENERALLY REQUIRES THAT THE VERTICAL STRESSES IMPOSED ON THE INFERIOR MATERIAL AND THE VERTICAL DEFLECTIONS INDUCED ON THE SURFACE BE WITHIN ALLOWABLE LIMITS SO THAT NEITHER SHEAR FAILURE NOR EXCESSIVE SETTLEMENT WILL TAKE PLACE. THE INFLUENCE CHARTS WERE DEVELOPED USING BURMISTER'S TWO-LAYER ELASTIC THEORY. THE STRESS AND DEFLECTION WERE COMPUTED USING AN IBM 360 COMPUTER AND THE RESULTS PRESENTED IN THE FIGURES.
