DESCRIPTION:Mohammadreza Khanmohammadi\, PhD in Geotechnical Engineering\,
  Amirkabir University of Technology (Tehran Polytechnic)\nPenetration of p
 refabricated piles in saturated clay leads to significant alterations in s
 tress state of the surrounding soil during and after the pile installation
 . Generation of excess pore water pressure (EPWP)\, its dissipation and th
 e stress state variations result in important changes in pile capacity. In
 creasing pile bearing capacity over time that is known as “soil setup”
  is of great importance in engineering practice. Various parameters such a
 s type of pile\, pile diameter and behavioral properties of the soil can a
 ffect rate of bearing capacity variations with time which is called “set
 up ratio”. In this study\, effects of pile diameter and Over Consolidati
 on Ratio (OCR) on variations of stress state in the soil and pile bearing 
 capacity are evaluated.\nA numerical finite element model (FEM) has been u
 sed to simulate a pile penetration in saturated clay and subsequent pore w
 ater pressure dissipation. Reasonable agreements between the numerical ana
 lysis results and laboratory tests and field data are indications of the r
 eliability of the numerical results.\nBased on the results\, a series of e
 quations have been extracted for determination of “coefficient of latera
 l soil pressure” at two different times (end of penetration and end of c
 onsolidation) and “setup ratio”.
