Abstract

Due to the importance of settlement control in Strip foundation, especially in soils that do not have the necessary strength, to build structures on such soils, there are various methods to reduce settlement, including these methods, soil improvement using additives. In this research, glass fiber additives have been used to stabilize the clay in order to reduce the settling in the Strip foundations due to the improvement of strength parameters. The combination of Glass fibers with clay and the effect of using this additive on the stabilization of clay fine-grained clay (CL) were investigated in the laboratory. Soil samples in the natural state as well as in the combined state with different percentages of Glass fibers equal to 0. 2, 0. 4, 0. 6, 0. 8 and 1% of the dry weight of the soil are used for laboratory tests including standard compaction test, California load ratio test as well as direct shear. The results show a decrease in unit weight of maximum soil and an increase in optimum moisture content, as well as a California load-bearing ratio by adding this material to the clay. The amount of cohesion and internal friction angle resulting from the direct shear test increase with increasing percentage of Glass fibers. After laboratory studies, the effects of using modified soil with improvement depths of one meter, two meters, four meters for Strip foundations with widths of 0. 75, 1. 50 and 2. 25 meters with the help of Plaxis2D software show that by increasing the percentage of glass fiber mixing. In fine-grained clay soils, the amount of foundation deposition is reduced, while the reduction of foundation deposition on soil mixed with 0. 8% Glass fibers is more than soil mixed with 1% Glass fibers. The reduction rate of Strip foundation with a width of 0. 75 m with a mixing percentage of 0. 8 Glass fibers and a depth of improvement of 4 m is 1. 57 cm. Also, the reduction rate of the desired foundation settlement with widths of 1. 5 and 2. 25 meters is equal to 2. 29 and 2. 72 cm, respectively.
