BAZALT FİBER KATKISININ SİLTLİ ZEMİNLERİN DRENAJLI KAYMA DİRENCİNE ETKİSİ

Soil remediation is usually a economically alternative for deep foundations that requires advanced technology. However, soil stabilization is frequently used under transportation structures. The use of additive materials in the improvement of soils is still frequently used today. In this context, natural and artificial fibers can be given as an example to additive materials used for soil improvement. It is also desirable that the material used for stabilization be environmentally friendly. Although basalt fibers developed in recent years are countable within this category, there is not yet enough study done on their use in ground improvement work. In this study, the effect of basalt fiber addition on the soil shear resistance on saturated silty soil specimens was investigated. Soil taken from a depth of 2-3 m in the city center of Adapazarı was consolidated in a saturated condition with basalt fiber material both in natural condition and in different proportions and reconstituted soil samples were formed. In one dimensional consolidation procedure, the vertical stress was chosen as 100 kPa. Shear box experiments were performed on the prepared specimens under different vertical stresses and shear resistance parameters were obtained. The experimental results show that 1.5% of the fiber additive is the most suitable in terms of shear resistance. As a result, it has been understood that the use of basalt fiber may be an alternative for improving soil properties.
