Tunnel Cross Section Area

Question

I have to calculate cross section Area to a Circler TBM Tunnel as m^2/m to Find EA and EA How can I calculate 
 I have E,v, diameter and thickness parameters

Hi Umit, 
 We assume that the plate used to model the tunnel lining has a rectangular cross-section. Therefore, the section area will be equal to: 
 A = b x d = (1m) x d, where b is the dimension of the model in the out-of-plane direction and d is the thickness of the lining. 
 Conversely, the moment of inertia is equal to: 
 I = (1/12) x b x d^3 = (1/12) x (1m) x d^3
