Effect of Crude Oil on Some Consolidation Properties of Clayey Soil
نویسندگان
چکیده
The study has been carried out with two broad objectives – to observe the effect of crude oil contamination on consolidation properties of soil and to predict the change in the properties in the form of mathematical correlation. The properties studied here are co efficient of compression (Cv) and compression index (Cc). Four types of naturally available soil (CH, CL, CI and SC) collected from different parts of Assam, India were used for this study. Laboratory tests were conducted on uncontaminated soil samples and soil samples contaminated at different level of contamination. Change in the properties of crude oil contaminated soil was observed. Variance analysis was performed and insignificant relationship between soil properties and level of crude oil contamination was discarded. Significant relationship between Cv and level of contamination was observed only in case of CL type of soil. Mathematical correlation between the soil property and the level of contamination was also determined. Coefficient of compression was observed to decreases linearly with the increase in the percentage of crude oil contamination. Change in compression index was not statistically significant. Keywords-Coefficient of compression, compression index, variance, correlation, significant.

Effects of Degree of Consolidation and Anisotropic Consolidation Stresses on Shear Modulus and Damping Ratio of Cohesive Soils at Low Strain
During consolidation process of saturated cohesive soil the soil stiffness increases. Increase of the effective stress due to dissipation of excess pore pressure causes additional stiffness of soil mass. This phenomenon has a very important effect on the behavior of saturated cohesive soils during dynamic loading. In the current investigation the changes in maximum shear modulus. Gmax and dampi...
متن کاملEffects of Glass Fiber Reinforced Polymer on Geotechnical Properties of Clayey Soil
Soil reinforcement can be considered as the combination of two parts. One part is soil for compressive stress capacity and another part is some material such as geosynthetics such as steel belts and fibers for tensile stress capacity. Soil improvement is one of the useful methods to increase the strength parameters of the soil. The main goal of this study is to evaluate the effects of GFRP on t...

Geotechnical engineers, in many cases face with low strength or high swelling potential of clayey soils. Stabilization methods are used to improve the mechanical properties of this type of soils. Lime and cement are the most popular materials used in chemical stabilization of clayey soils. If sulphate exists in the stabilized clayey soil with lime, or if soil is exposed to sulphates, problems s...
