Estimating and Costing - Engineering

Q1:

A portion of an embankment having a uniform up-gradient 1 in 500 is circular with radius 1000 m of the centre line. It subtends 180° at the centre. If the height of the bank is 1 m at the lower end, and side slopes 2:1, the earth work involved.

A 26, 000 m3

B 26, 500 m3

C 27, 000 m3

D 27, 500 m3

ANS:D - 27, 500 m3

Assume semi-circle plan, embankment section of a triangle with 1 m ht and 1 m base, so the total length of the embankment is π* 1000m, so final section with triangle ht 6.283 m.

Then solve, you will get the answer.
