Abstract:

THE STANDARD PENETRATATION TEST IS WIDELY USED THROUGHOUT THE WORLD BY GEOTECHNICAL ENGINEERS TO OBTAIN COST EFFECTIVEDATA CONCERNING THE VARIOUS PHYSICAL PROPERTIES OF SOIL RELATING TO ITS BEARING CAPACITY. THIS INFORMATION IS USED IN THE DESIGN OF FOUNDATIONS AND ACCURATE DATA IS, THEREFORE, OF CRITICAL IMPORTANCE. NUMEROUS STUDIES HAVE CONCLUDED THAT THE INSTRUMENTATION CONVENTIONALLY EMPLOYED IN CONDUCTING THE STANDARD PENETRATION TEST HAS SEVERAL INHERENT FLAWS WHICH RESULT IN NON-RELIABLE DATA. THE OBJECTIVE OF THIS RESEARCH IS TO FIELD TEST AN INNOVATIVE STANDARD PENETRATION TEST INSTRUMENT WHICH HAS BEEN DESIGNED TO ELIMINATE THE DEFICIENCIES OF THE CONVENTIONAL EQUIPMENT. THE NEW INSTRUMENT, CALLED THE ACCU-HAMMER, WILL BE USED TO CONDUCT THE STANEARD PENETRATION TEST THROUGH THE SAME SOIL PROFILE TESTED WITH ACONVENTIONAL INSTRUMENT. THIS WILL BE DONE AT SEVERAL SITESAND DEPTHS SO THAT A LARGE AMOUNT OF DATA, INCLUDING A WIDE RANGE OF FIELD CONDITIONS, CAN BE GENERATED. WHEN A COMPARISON OF THE DATA PRODUCED BY THE CONVENTIONAL AND ACCU-HAMMER SYSTEMS IS MADE, IT IS ANTICIPATED THAT THE ACCU-HAMMER WILL BE MUCH MORE CONSISTENT. IMPROVED ACCURACYIN STANDARD PENETRATION TEST DATA WILL YIELD MORE STABLE FOUNDATION DESIGNS AND REDUCE ECONOMIC LOSS RESULTING FROM FOUNDATION FAILURES.
