Soil Cover for Tunnels
Soil Cover for Tunnels
(OP)
What should be minimum cover criteria for tunnels in soft clay?
In our present problem, the soil cover above TBM tunnel is ~1D and we are planning to construct a subway above the tunnel when the cover between Tunnel Crown & Subway bottom will be <1D.
Our concern is what should be the stability issues considered in design & construction period.
