Abstract

Expansive soils are highly susceptible to volumetric changes leading to rapid loss in the bearing capacity of footings resting on them. Among several techniques available to treat expansive soils, lime or fly ash stabilization gained prominence during the past few decades due to its abundance and adaptability. Chemical stabilization is widely used to treat expansive soils as it develops base exchange and cementation processes between clay particles. When expansive soils are treated with chemicals, it is essential to obtain the load-settlement response of footing resting on stabilized ground. In this study, Finite Element Analysis is performed using the commercial software, PLAXIS 2D, to obtain the load-settlement response of a strip footing resting on untreated and treated expansive soil. The bearing capacity of strip footing resting on treated soil is found to be about 150% higher than that of footing resting on untreated soil.
