摘　　要：In the present, investigation an attempt has been made to study the behavior of reinforced flyash beds under repeated loads by conducting carefully designed experiments. The main objective of the experiments conducted is to evaluate the beneficial effects of using flyash as a backfill material in the reinforced beds to resist the repeated loads. As no unique standard equipment is available for the application of repeated loads and to measure the response, different researchers have designed and fabricated different types of equipments for the testing. The repeated load of known intensity with waveform type and frequency is applied on the surface and embedded footing in unreinforced and reinforced flyash beds. The response of the flyash beds, in the form of settlement is measured using linear variable differential transducers. The experimental results clearly demonstrated that the provision of reinforcement in the flyash beds is effective in improving the performance of both surface and embedded footing under repeated loads.
