| چکیده | ||
| Utilization of landfills for possible construction projects requires investigation and improvement of geomaterials in these areas. In this research, the effects of lime on improving the behavior of soil materials in Isfahan landfill were investigated through a series of laboratory experiments. Unstabilized and stabilized samples with 3 %, 6 % and 9 % lime were tested. Direct shear tests under different overburden and falling head permeability tests were conducted. X-ray diffraction tests were also performed to check the structure of the samples. Also, the scanning electron microscope images of the tested samples were prepared and compared. The results indicate that the lime-stabilization improves the stress-strain behavior of the treated samples. At the strains greater than 1 %, the positive effect of lime-stabilization of treated soil samples is obvious. Tests results indicate that the optimal amount of lime for Isfahan landfill’s soil stabilization is 6 %. Stabilization of samples with 6% lime under vertical overburden stresses of 0.5, 1 and 2 kg/cm2 increases the maximum shear strength of the samples by 113.95 %, 30.95 % and 9.88 %, respectively. The results show that the permeability coefficient of stabilized samples decreases with the increase of lime content. Stabilization using 3 %, 6 % and 9 % lime has resulted in a decrease of 14.66 %, 84.83 % and 93.62 % of the permeability coefficient of the landfill soil samples compared to the unstabilized samples, respectively. The results also show that the decreasing rate of permeability coefficient is increasing up to 6 % of lime and beyond that has decreased. | ||
