Effects of Fibre on Strength Properties of Soil at Different Depth of Soil Layers

Construction of building and many civil engineering structures on weak or soft soil is very risky and dangerous on geo-technical grounds because this type of soil is take place settlements, poor bearing capacity, weak strength parameters and high compressibility of soil. Improvement of load bearing capacity of the soil may be undertaken by a variety of ground improvement techniques like soil stabilization, vibroflotation and fiber reinforced earth technique of soil etc. fiber reinforced earth technique is a very effective ground improvement technique because of its cost effectiveness, easy adaptability and reproducibility and workability etc. Therefore, In this Research paper, it is experimentally carried out to investigate the effects of the fiber on engineering properties of the soil at different layers. Polypropylene fiber has been used as the reinforcement material and it was included in to the soil at two different layers, i. e.0, 40, 80 mm. The main objective of this investigation had been focused on the strength behavior of the soil reinforced with polypropylene fiber. The fiber reinforced soil samples were subjected to compaction, permeability, shear strength and California Bearing Ratio (CBR).
