Cut and cover tunnel

Cut and cover tunnel designed with DeepEX

A cut and cover tunnel example will be analyzed with DeepEX. The following data is available:

a) Soil properties: Sand, friction angle = 30 degrees, total unit weight 120 pcf, loading modulus of elasticity Eload= 300 ksf, reloading modulus of elasticity Eur = 900 ksf. Ultimate bond resistance for ground anchors 40 psi.

b) Excavation depth: 20 ft between two diaphragm (slurry) walls that are constructed with a spacing of 20 ft, slabs at 1.5 ft depth and 18.5 ft depth.

Objective: Design the walls and slabs with allowable stress methodology and obtain a wall embedment safety factor of 1.5.
