Abstract
One of the significant development indicators in each region is the existence of various transport systems and their accessibility. Among the various transportation methods, railroad transport due to unique advantages has attracted the attention of country policy makers. And the development of the railways network is on the agenda. To expand the railway networks, construction of railway tracks on the loose subgrades is one of the inevitable issues. Among the various soil improvement methods, stone columns due to implementation and economic efficiency are of interest. This method increase the bearing capacity and reduce the settlement of the loose subgrade soil and improve operation quality. In this investigation has studied the influence of presence of stone columns in term of reduce the dynamic response of loose sandy subgrade soil under the train path. This investigation results show that stone columns the maximum reduce in the vibration parameters of loose sandy subgrade soil such as vertical displacement, amplitude range of vertical velocity and acceleration are respectively 19/20, 27/85 and 41/74 percent.
