Abstract
In this paper, the deformation behavior of Solani river sand and the effects of geogrid reinforcement under cyclic loads are investigated. The effects of dynamic loading parameters on Solani sand were determined in dry and saturated condition. The effects of geogrid on properties of sand were analyzed. Samples were prepared in a shake table having test bin of dimension 1.05 m × 0.6 m × 0.6 m. The shake table could produce horizontal vibration with various frequency and acceleration. Results on dry sand indicated that the volumetric strain varied as a function of acceleration and number of loading cycles. Volumetric strain of dry sand samples reduced significantly by reinforcing with geogrid sheets. The response of saturated samples under cyclic loading were observed. Samples reinforced with geogrids showed reduction in pore water pressure and settlement. The effects of number of cycles on volumetric strain and pore water pressure on unreinforced and reinforced samples were analyzed.
