A CONSOLIDATION STUDY

A LITERATURE AND SETTLEMENT DATA STUDY HAS BEEN MADE TO CORRELATE VARIOUS CONSOLIDATION THEORIES WITH ACTUAL FIELD SETTLEMENT ANALYSIS AND OBSERVATIONS. THE ANALYSIS OF THE LITERATURE AND ITS PERTINENT DATA HAS INDICATED THAT THE CLASSICAL THEORY OF CONSOLIDATION PRESENTED BY TERZAGHI IS THE BEST EXPLANATION SO FAR AS THE PRIMARY CONSOLIDATION IS CONCERNED. SECONDARY CONSOLIDATION THEORIES ADVANCED BY VARIOUS RESEARCHERS ARE CONFLICTING. SOME ARE BASED ON THE TEST RESULTS OF VERY FEW SPECIMENS AND THEY LACK STATISTICAL PROOF, WHILE OTHERS COVER SPECIFIC CASES. HOWEVER, IT HAS BEEN ESTABLISHED THAT THE EFFECT OF THE SECONDARY COMPRESSION IS VERY PRONOUNCED, ESPECIALLY IN ORGANIC CLAYS, AND IT SHOULD NOT BE DISREGARDED IN THE ANALYSIS OF SETTLEMENT DATA. THE LOGARITH OF TIME FITTING METHOD WAS FOUND TO BE UNSUITABLE FOR THE ANALYSIS OF SOILS STUDIES. THE SQUARE ROOT OF TIME FITTING METHOD HAS PRODUCED SATISFACTORY RESULTS. IT HAS ALSO BEEN INDICATED AS A RESULT OF THIS STUDY THAT THE SECONDARY COMPRESSION IS NOT LINEAR AS ASSUMED BY VARIOUS AUTHORS. /RRL/A/
