Bearing Capacity of A Strip Footing Resting On Treated AndudUntreated Soils

摘要

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