Optimum Design of Port Railway Subgrade Applying to Soft Base
Being restricted by the dredger-filled soft base with poor bearing capacity,higher requirements is made for the design of port railway subgrade.Though port railways serve heavy-load freight,most of them belong to end line or loading&unloading line,are characterized with low running speed.Based on a railway subgrade works in Huanghua Port,the basic design plan of soft-base subgrade is improved and analyzed from the aspects of technology and economy,which leads to the optimized port railway subgrade that adapts to soft base,meets the bearing capacity requirements,and is more economical as well.The research results will be applied in similar projects.
