| Abstract | An experimental study of the compressibility of Bangkok
Clay in the weathered zone was carried out using the one-dimensional consolidometer without pore pressure measurement. All the test specimens were obtained from the new AIT site at Rangsit, 42 kilometres from Bangkok. Apart from the series of standard consolidation tests that was carried out to investigate the effect of sample depth, tests were designed to show the effects of the loading conditions on the test results. To this end, load· increment ratios of 0.25 to 2.0 and load increment durations of one day to seven days were employed. The test results show that the soil compressibility
increases with depth and is unaffected by the loading conditions. There exists an apparent preconsolidation pressure in the Weathered Clay which decreases with depth and which is a function of the degree of weathering and its effect on soil particle cementation. The coefficient of consolidation and the coefficient of secondary compression were found to be functions of the load increment duration, the load· increment ratio and the effective
pressure. The results reflect the significance of particle
bonding and particle structure on the consolidation characteristics of the Weathered Clay. |
