The role of dilatancy in shallow overburden tunneling

The mechanical behavior of sandy ground during shallow circular tunneling is explored for various overburden heights H (=0.5D, 1.0D, 1.5D and 2.0D; D is the diameter of the tunnel) and various dilatancy coefficients (ψ/ϕ = 0, 1/3, 1/2, and 1; ϕ and ψ are the internal friction angle and dilation angl...
