Abstract: Presence of soft clayey soil poses a problem for the construction of high load structures due to its low bearing capacity and high settlement. The soil should hence be stabilized to enhance its bearing capacity and decrease the settlement to make it suitable for construction. This study focuses on the behavior of geosynthetic reinforced-clayey soil and also the effect of different parameters contributing to their performance using laboratory model tests. The parameters investigated in this study are the type of geosynthetic reinforcement andthe number of reinforcement layers / vertical spacing between geosynthetic layers. Laboratory Tests were performed to examine the efficiency of geosynthetics and the effect of their spacing on the peak load bearing stress of soil. A series of model tests were conducted to investigate the behavior of the geosynthetic-reinforced clay under circular type of loading. Tests were conducted by preparing soil specimens reinforced with geotextiles, geogrids and geocomposites at various spacing and were tested for their load bearing capacity. The test results show an enhancement in load carrying capacity and depletion in settlement of soil when reinforced with the geosynthetics. Based on the results of the experimental program, the effect of spacing in increasing the load carrying capacity of clayey soil is established. The results of this study may be helpful in improving the bearing capacity of highly compressible soft soils and also in reduction of layer thickness in pavement design on soft clayey soil
