A tunnel runs inside an embankment that supports a highway, as shown in Figure P14.13. The equivalent hydraulic conductivity of the embankment soil is k = 8 ×10-5 cm/s.

(a) Draw the flow net within the embankment for the worst-case scenario.

(b) Determine the uplift force per unit length at the base of the tunnel.

(c) Determine if piping would occur if the unit weight of the soil in the embankment were 18.8 kN /m3.
