Abstract
The performance and behavior of reinforced soil structure, both in the field and the laboratory are well documented. In the field situation, when the reinforced sand beds are used as a construction tool or as a ground improvement method, it is often the situation that they are subjected to the effect of water. In this study series of repeated load tests were conducted on mild steel square footing of 100mm size resting on a sand bed placed in a 500mm-dia, 390mm deep mild steel tank. Reinforcement location and spacing were selected based on optimization of previous research results. The sand beds were inundated to different levels viz full and partial. The results of the experiments demonstrated the impact of pressure of water on the performance of reinforced earth when subjected to repeated loading. The reinforced sand beds are very efficient under the repeated loads and the presence of water table has a considerable influence on their performance. The cyclic resistance ratio of the reinforced sand bed increases and the settlement ratio reduces considerably, when reinforcements are introduced in them.
