For calculating the cross-sectional area, most of the time we depend on Auto Cad, as well as various hectic calculations.

From my past experiences and as per knowledge, the short-cut calculation has been developed, called as AREA CBS FACTOR, the calculation has been shown below……..

C/S AREA OF HORSE SHOE SHAPE TUNNEL =  d2 X CBS FACTOR

Where,

d = Dia. Of horse shoe shape tunnel

CBS FACTOR = 0.829323611

From above formula, we can calculate Area instantly with simple multiplication.

For example….

For a 6mt. dia tunnel, the Area has been calculated…

Area = d² x 0.829323611

             6² x 0.829323611 ->   29.85 m²

The above calculation can be verified using Auto-Cad or any mathematical technique
