An investigation on the geomechanical properties of fiber reinforced cohesive soils

Abstract

In recent years, the use of natural and synthetic fibers in soil improvement has become widespread in soil mechanics applications. Easy to use and low cost fibers have been the subject of many geotechnical researches in recent years. In this study, results of previous mechanical experiments performed on fiber-cohesive soil mixtures were reviewed in a systematical approach. Based on the data derived from the experimental studies available in the literature, it has been observed that various soil properties including soil strength have improved with increasing density of the fibers up to a certain level. The percentage of added fiber has a significant effect on improving soil properties. Based on statistical analysis, simple correlation relationships were suggested based on the investigated test database.
