Effect of Diesel-Oil Contamination on Shear Strength and Compressibility Behavior of Sandy Soil


Salah A. Taqieddin;


An experimental study was conducted to evaluate the effect of degree of diesel-oil contamination on deformation and strength of well-graded sandy soil with silt. The effects of contamination on shear strength and compressibility, in particular, have been thoroughly investigated in this study. The test results indicated that the shear strength parameters could be adversely affected by diesel-oil contamination. The compressibility of soil, as revealed by the compaction test and the one-dimensional compression test, was significantly influenced by the addition of diesel-oil as pore fluid. However, this ongoing study has yet to concentrate more on some other variables, such as the degree of saturation, relative density and rate of applying strain energy to the varying degree of diesel-oil contamination, which were not sufficiently addressed. Recommendations for extending these parameters and others are suggested.
