Experimental Study on Improvement of Roadbed Fill for High-speed Railway by Utilizing Disposed Soil from River Beaches and Mudflats
In order to solve the environmental impacts caused by the river bank abandonment in the compensation project of Three Rivers and the shortage of fill material for the roadbed of the railroad Hongze and Jinhu Railway Station,it is proposed to improve the cut bank abandonment and use it as the roadbed fill material.Relying on the Ninghuai Railway project in Jiangsu Province,it is proposed to improve the cut bank abandoned soil and use it as roadbed filler.Different optimized improvement schemes of single mixed cement/lime,mixed cement+organic curing agent are adopted for the experimental study,and it is determined that the optimal improvement scheme of the abandoned soil is mixed with 5.0％cement(max.dry density of 1.78 g/cm3,optimal moisture content of 17.8％).
