Strength behaviour of granular column-reinforced soft soil subjected to lateral shear loading - Vol.52(6), Dec - USA Springer 2022 - 1450-1463p.
The behaviour of granular columns as soil reinforcement under compressive axial loading is well documented. However, the different forms of lateral soil movements occurring in soft soil cause lateral force on granular columns, resulting in shear deformations. Minimal comprehensive direct laboratory research in this area forms the motivation behind this work. This experimental study is focused on the contribution of granular column reinforcement to the shear strength of the soft ground. For this purpose, a series of large-scale direct shear tests with 300 × 300 mm sample dimensions were performed in the laboratory. Effect of variables like normal stress, characteristics of granular column infill material, and column configurations (single, triangular, and square) was studied. Test results obtained from this experimental study are presented in terms of the increase in the overall shear resistance of the soil-column matrix and increase in the shear strength parameters. The experimental test results showed higher values than the values predicted from analytical equations.
