Question

A railway embarkment of formation width of 10m and side slope 3:1 is required to be made on a ground which is level in a direction traverse to the centre line. The central heights at 20m intervals are as follows; 0.5, 2.5, 3.00, 5.0, 4.0, 3,20 and 0.4. Compute volume of earth works

Answer #1

2.
An embankment of width 10m and side slope 1 1/2 : 1 is required to
be made on a ground which is level in a direction traverse to
centre line. The central height at 20 m intervals are as follows:
0.8, 1.2, 2.25, 2.6, 1.9, 1.4 and 0.9. Calculate the volume of
earth work according to prismoidal formula.

The formation width of a road is 15 m, and the side slope for
cutting is 1.5:1 and for filling 2:1. The transverse slope of the
ground is 1 in 6 (rise). The sections are 70 m apart. The depths of
excavation at the centers of the two sections are 0.75 m and 1.15
m, respectively. Find the volume of cutting and filling.
