Research on Anti-frost Design for Railway Subgrade in Seasonal Frozen Earth Area |
| |
| Abstract: | To solve the problems of frost heave of railway subgrade in northwest and northeast China,the anti-frost design measures of Harbin-Dalian,Harbin-Qiqihar,Mudanjiang-Suifenhe railways are summarized.Based on the subgrade frost-heave deformation monitoring results of three railway lines,it is concluded that the frost heave deformations are properly controlled.Design suggestions for selection of anti-frost filling materials and design depth of anti-frost are proposed. |
