| Abstract | This thesis is a study of the regional subsidence in the Bangkok Metropolitan area due to ground water extraction. The Bangkok Metropolitan area are
divided into three regions, namely, Bangkok, SamutPrakarn and Rangsit. In each area, the available data are collected and related together to find, by visual inspection, the probable values used in the calculation for that
area. The mentioned data include soil profile, total unit weight, specific gravity, void ratio, preconsolidation pressure, e-log p curves, and piezometric
pressure variation. For the soils where data are not obtained directly, they are found indirectly by extrapolation of known corresponding data of the
shallower soils. The calculation is done for all regions for two assumed modes. The calculation of ultimate primary compressions of the Soft Clay using generalized soil profile, general properties, and compression characteristics
is found to give good results when compared to the calculation using specific
values for individual sites. The present subsidence values obtained seem to be too high when compared to the observed value of 16 cm, but the combined compressions of the Soft Clay and Stiff Clay layers are very near to this value.
This may prove that the subsidence consists only of the compressions of the Soft Clay and Stiff Clay layers. |
