Title: INFLUENCE OF COMPRESSION AND SHEARING STRAINS IN SOIL FOUNDATIONS ON STRUCTURES UNDER EARTH EMBANKMENTS
Accession Number: 00235366
Record Type: Component
Abstract: WHEN AN EARTH EMBANKMENT IS CONSTRUCTED ON A SOIL FOUNDATION, THE WEIGHT OF THE EMBANKMENT PRODUCES COMPRESSION AND SHEARING STRESSES IN THE FOUNDATION. THE STRAINS INDUCED BY THESE STRESSES CAUSE SETTLEMENT OF THE NATURAL GROUND SURFACE AND AN OUTWARD MOVEMENT OF THE FOUNDATION SOIL FROM THE REGION OF THE CENTERLINE OF THE EMBANKMENT TOWARD THE TOES OF SLOPE. THESE SETTLEMENTS AND OUTWARD MOVEMENTS HAVE IMPORTANT IMPLICATIONS IN CONNECTION WITH THE DESIGN AND PERFORMANCE OF THE EM- BANKMENT AND OF STRUCTURES UNDER THE EMBANKMENT, SUCH AS CULVERTS AND SLUICEWAYS. VERTICAL SETTLEMENTS EFFECT THE SHRINKAGE ALLOWANCE IN EMBANKMENT DESIGN AND INFLUENCE THE CHOICE OF AN APPROPRIATE AMOUNT OF CAMBER IN THE FLOW LINE OF A CULVERT. THE OUTWARD MOVEMENTS DUE TO HORIZONTAL SHEARING STRAINS MUST BE TAKEN INTO ACCOUNT IN THE DESIGN OF TRANSVERSE JOINTS IN THE BARREL OF CULVERT. THE AMOUNT OF SETTLEMENT AND LENGTHENING OF 46 CULVERTS AND SLUICEWAYS ARE RECORDED IN THE PAPER. /AUTHOR/
