The load increment ratio was varied from 0.25 to 4.0, while the load increment durations used were 24 hours and 48 hours. It was found that the rate of pore pressure dissipation was function of load increment ratio, as predicted theoretically by BARDEN & BERRY (1965), DAVIS & RAYMOND (1965) and  SIMONS & TAN (1969), the smaller the load increment ratio, the faster the rate of pore pressure dissipation. The available theories, however3  did not generally predict the pore pressures very well and it was concluded that Terzaghi's theory might as well be used for all loading conditions. The measured effect of load increment duration on the rate  of pore pressure dissipation was insignificant. An attempt was made to estimate coefficients of consolidation from rates of pore pressure dissipation and these were compared with those  obtained in the conventional way from the compression time curves. 0aSoil consolidation 0aClay1 aBrand, E.W., eChairpeson1 aMoh, Za-Chieh, eExamination Committee1 aNelson, John D., eExamination Committee2 aGovernment of the Republic of  China, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno. 378  3Full-Textuhttp://203.159.5.9/ait-thesis/detail.php?q=B24303
