| Abstract | An experimental investigation was carried out to study the effect of soil structure on consolidation behavior of soft clays. Samples of soft Bangkok Clay were artificially sedimented in the laboratory. Five different soil structures were produced by sedimentation in solutions of sodium chloride, calcium chloride, sodium hexametaphosphate, in fresh water and leaching of a sodium chloride sediment. One-dimensional consolidation tests with back pressure application and pore pressure measurement were performed on the sedimented soils with different load increment ratios. A conventional lever-arm consolidation test was also performed on each type of the soils. The tests results showed that the characteristics of the compression-pressure relationships of all the five soils are similar to that of the undisturbed Soft Bangkok Clay. The effect of soil structure on compressibility of the clays was not found to be so significant. The coefficient of consolidation as well as the rate of pore pressure dissipation, however, were found to be affected by the soil structure. The coefficient of secondary compression was also found to be affected by the soil structure. |
