An Experimental Study on Fly Ash Slope

Prajwala S. Chachadi, Prasanna Patil

Abstract


In India thermal power plants are facing the difficulty in disposal and utilization of Fly ash only some part is utilized for construction works. In present study Fly ash is used for stabilization. Model tests are conducted with different proportion of Fly ash and soil sample. Different percentage of Fly ash is mixed with soil (10%,20%,90%.) by it’s dry weight and when Fly ash is mixed with soil OMC decreased and MDD is increased .In the present study the model box of 70cm*50cm*40cm is used .The Plastic scraps and geo grids are used as reinforcement materials. The square footing of 10cm*10cm*0.1cm is placed at 2 cm away from steep slope at two different angles 60° and 45° respectively. The load carrying capacity and settlement is determined and from data load v/s settlement graphs are plotted. From experimental work the factor of safety is determined from Swedish slip circle method and FOS of geo grid of reinforced slope is more i,e. 2.15 and 2.46 for angles 60° and 45° respectively.
