Evaluation on the Shear Strength Characteristics of Soil Reinforced with Randomly Distributed Areca Fibers
The strength and stiffness of soil can be improved with soil reinforcement. Inclusion of natural and synthetic fibers in the weak or problematic soils as reinforcement can improve the geotechnical properties of the soil. Fiber distribution in random manner is the most simple and convenient method for reinforcing soil. This paper investigates the effect of natural areca fiber in improving the shear strength of soil by conducting a series of laboratory direct shear tests. The areca fiber used in the study was single fibers having an average length 2–3 cm. All the tests were conducted under normal stresses of 50, 100, and 150 kPa and at a relative density of 50%. The fiber content was varied from 0.5 to 1.5%. The results showed that the cohesion and angle of internal friction of fiber reinforced soil were improved compared to unreinforced soil. At an optimum fiber content of 1%, the shear strength of reinforced soil improved by 34.72, 30.36, and 30.63% compared to unreinforced soil under normal stresses of 50, 100, and 150 kPa, respectively.
