BEHAVIOUR OF FIBRE REINFORCED LATERITIC SOIL UNDER CIRCULAR FOOTING. REINFORCED SOIL AND GEOTEXTILES, PROCEEDINGS OF THE GEOTEXTILES CONFERENCE HELD AT THE INDIAN INSTITUTE OF TECHNOLOGY, BOMBAY, INDIA, DECEMBER 8-9, 1988

The concept of reinforced earth for improving the bearing capacity of in situ soils and controlling settlement, has gained popularity in recent years. In the present investigation one of the synthetic fibres available under the commercial name "synthetic twine" is used as reinforcing material to improve the carrying capacity of locally available lateritic soil. The reinforced soil contains discontinuous, discrete and randomly orientated fibres with an aspect ratio 40. Treating this soil mix as a homogeneous and anisotropic material, the effect of inclusion of fibre reinforcement on the strength and deformation characteristics of lateritic soil has been studied. 1%, 2% and 3% fibres by weight of dry soil are used. Circular cement concrete footing of 150 mm diameter is adopted to transfer the load to the compacted reinforced soil. The test results indicate that the ultimate bearing capacity increases with 1% and 2% fibre. 3% fibre inclusion causes a sudden decrease in the bearing capacity value. The elastic settlement decreases with 1% and 2% inclusion of fibres whereas it increases with 3% fibres. For covering abstract of the conference, see IRRD 836241. (Author/TRRL)
