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

awesome..quite helpful..
What we do for ourselves dies with us - What we do for others remains, and is IMMORTAL...
this will definitely proves to be a great research... !!
may can help people in the world calculate more easy tunnel horse shoe shape without computer. Good luck!!!
Thanks and Please go through www.cbsinghhydroblogspot.in, it will be help for calculationing the area of Horseshoe Shape,
Thanks
Waawoooooo.... very f9

Dear Mr. Ratnesh Thakur, Every invention requires an authentication, and I will gladly accept any sort of authentication/proof for this formula by your side, through any valid source/print media. This idea originally generated in 2002 but I didn't have intention to publish it....
thank you sir for posting these great formula. it'll be really helpful to all students as well as engineers & other professionals. it saves time & hectic calculations.
keep posting these types of formulas sir.
thank you once again. :)
Dear C B Singh sir
You are really king of Tunnel.
cb sir plz tell me how to calculate factor for tunnel
Sir you covered a nice topic about "AREA CALCULATION FORMULA OF TUNNELS CROSS-SECTIONS". I am agree with your statement. it will very helpful to calculate the area of cross section.
Dear Sir,
I found the formula is very use full in calculating tunnel perimeter and area, i wish u, all the best towards your journey to imparting knowledge with others. Many Regards
Sir ye to tunnel ke bare me bahut achhi jankari hai age bahut kam ayga ye

can any body tell me what is cbs factor????
Dear Sir
I would like to inform you that "CBS" means Chandra Bhushan Singh which is my name, of course, these formulas are generated by me, that is why I have given the name of this factor "CBS FACTOR".
Thanks for recalling me and for any suggestions, I will be oblige.

Thank you sir for posting thise great formula.This is very useful formula for tunneling engineering.
But can i use this formula for calculating C/S AREA OF HORSE SHOE SHAPE TUNNEL.
Radius X Radius X 3.317293(FACTOR)
Dear Mr Prosenjit Koley
I preciate you for calling me, you may use, both are same.
Thanks
CBS
Great! Expect more informative ideas.
Thanks and regards

Sir in IS 4880 - II FOR D SHAPE area they have used 0.905d^2,and for perimeter 3.58d^2.
Is that also correct
Amazing and helpful
