| Abstract | This research tried to investigate the relationship between the residual negative pore pressures in undisturbed clay samples and the in-situ (overburden) vertical effective stresses und.er which the samples were existing under the ground. The residual negative pore pressures in the samples were measured employing a newly proposed technique which essentially relies on the time lag characteristics in measuring pore water pressure. Soft and stiff Bangkok clays taken from Silom Road (Bangkok ) , and weathered and soft Bangkok clays sampled under the embankment and outside the embankment at AIT (Rangsit) were used in this investigation . The results show an indication of a unique proportional relationship between the in-situ vertical effective stress and the residual negative pore pressure foe uniform (homogeneous) clay samples which received the same methods and conditions from sampling through laboratory testing. This relationship can be used as a means of indirect measurement of in-situ effective stress states and could be used to check the stress states estimated by some numerical techniques. |
