Performance of Granular Pile Foundation System for Expansive Soil
摘要
The bearing capacity or resistance of structures built on the expansive soil determines the stability of the soil. The structure fails due to the insufficient bearing capacity of the soil. As a solution for this, granular pile was installed in soft clays to overcome the problems like load bearing capacity, settlements, and swelling of the expansive soils. The laboratory test was conducted on expansive clay by varying the diameter of the stone column. The results revealed that bearing capacity increases, swell pressure decreases, and settlement decreases (79.13%) with the increase in the diameter of the stone column. The proposed granular pile method appears to be a practical means of ground improvement based on the results of a field test on black cotton soil.
