Popis: Geocell is being used very conveniently for soil reinforcement and slope protection in the recent times. The main advantage of this synthetic material is provision of the confinement to the soil resulting in the higher resistance to shear failure of the soil. Geocell is a three-dimensional synthetic material having the varying wall thickness and opening sizes. The use of the confining properties of the geocell is needed to be investigated in the application of bearing capacity improvement of soil below the foundations. The present work demonstrates bearing capacity improvement of the soil using geocell as the confining reinforcement. A series of experimental model tests is performed in the present study with constant soil type (sand). Parameters considered for variation was the width (W), opening size (og) and height (hg) of the geocell. The image analysis was performed mainly in ImageJ which is available on free license program with Digital Image Correlation and the Particle Image Velocimetry approach. The observations were made mainly in terms of maximum load carried by the subsoil and the depth of Rankine’s zone obtained due to placement of geocell. Load bearing resistance of subsoil was in proportion with the width and height and in inverse proportion with the opening size of the geocell. The Rankine’s zone also observed to shift downward due to geocell inclusion providing more shear surface and thus higher bearing capacity. Thus, the geocell may successfully be utilized below shallow foundations to obtain higher Safe Bearing Capacities.
