Sandy soils cover large spaces in Iraq, and it is dry and weak. Building on these soils is risky since they are unstable, and the soil may collapse after loads are placed on it. To build on these soils, the soil must be improved and strengthened or reinforced. One of the most common soil improvement methods is the use of additives, but the use of chemical additives such as oil derivatives, plastics, and others are considered to be harmful to the environment. This research aims to enhance the engineering properties of sandy soils in Karbala, Iraq, such as shear strength and bearing capacity. by using jute fibers, which are environmentally friendly and recycled materials derived from plant fiber remnants, and it is also considered to be low-cost additives. Laboratory tests on reinforced and unreinforced soil were conducted. The variables examined in this study are the dimensions and thickness of footing, the dimension of jute fiber sheet, the depth of first layer of jute sheet and vertical spacing between reinforced layers. The results demonstrated that adding jute fibers to the soil improved its engineering properties significantly. The study also showed the possibility of using environmentally friendly materials such as jute fibers to improve and strengthen sandy soils in Iraq, particularly at shallow depths, as well as how plant fibers can be reused for engineering purposes.
