Response Analysis of a Ballasted Rail Track Constructed on Soft Soil by 3D Modeling

Figure 13

Color contours of the radial strain (a) without improvement of the subgrade or subsoil; (b) with the improvement of only the subgrade (E₅₀ subgrade = 100 MPa for the deltaic deposit); (c) with the improvement of only the subsoil (E₅₀L₁ = 35 MPa, E₅₀L₂ = 30 MPa; E₅₀ subgrade = 60 MPa); (d) with the improvement of both the subsoil and subgrade (E₅₀L₁ = 35 MPa, E₅₀L₂ = 30 MPa; E₅₀ subgrade = 100 MPa).
