| Laboratory testings, consisting of soil properties testing and vacuum consolidation testing with and without vertical wick drain, were carried out on five different types of soil to determine soil properties and relationship between settlement and time. One dimensional consolidation teat was performed to determine if this test could be used for predicting the behavior of soils during vacuum consolidation. From the results of this study, the one dimensional consolidation test does not appear to be suitable for predicting the rate of vacuum consolidation without wick drain. However, one dimensional consolidation test reasonably predicts the total settlement of vacuum consolidation without wick drain. In vacuum consolidation, the amount of the settlement for silty soils were more or less the same for both cases, with wick drain and without wick drain, even if the time required for consolidation was considerably different. And, strategic placement of wick drain ensures moisture content and the value of the density are similar throughout the soil sample. However, the presence of wick drain for clay Boils increased the amount of settlement and also shortened the time required for consolidation. |
