Abstract
This paper presents the results of laboratory model experiments on a circular foundation to better understand the performance of geocell reinforced expansive soil. The subsoil in this study was formed by naturally occurring expansive soil. To strengthen the soil bed, chevron-patterned geocells formed of polypropylene geotextile were used. Geocell mattress’s height, geocell mattress’s pocket size, and the geocell mattress’s placement depth were all investigated in this testing program depth. In contrast to previous researchers, the reinforced bed’s improved performance is determined to a settlement corresponding to the soil bed’s failure settlement without reinforcement. The factors, non-dimensional, such as; If “bearing capacity improvement factor” and PRS% “settlement reduction factor”, are used to evaluate the performance of reinforced beds. The use of geocell as a reinforcement caused a substantial bearing capacity increase as well as the decrease of footing settlement, as indicated by the test findings. The use of a geocell mattress of ideal proportions placed directly below the footing base increased the reinforced bed’s bearing capacity greater than 200% and reduced footing settlement greater than 81%. The present study highlights the use of geocells toward the stabilization of the expansive soil.
