THE SHAFT FRICTION OF PILES IN COHESIVE SOILS IN TERMS OF EFFECTIVE STRESS

IT IS SUGGESTED THAT THE LATERAL EFFECTIVE STRESSES IN THE GROUND CONTROL THE MAGNITUDE OF PILE SHAFT FRICTION WHEN RATES OF LOADING ARE SLOW ENOUGH TO ENSURE DRAINED CONDITIONS IN THE CLAY ALONG THE PILE SHAFT. THESE CONDITIONS ARE FULFILLED IN MAINTAINED LOAD TESTS AND, PARTICULARLY, IN LONG TERM, IN-SERVICE CONDITIONS. RESULTS OF PILE TESTS IN LONDON CLAY CONSIDERED IN RELATION TO THE AT-REST STRESSES IN THE CLAY ARE IN REASONABLE AGREEMENT WITH THE HYPOTHESIS. PILES IN NORMALLY CONSOLIDATED CLAYS ARE BRIEFLY CONSIDERED. /AUTHOR/
