In a railway cutting, the side slopes are 1.5:1 and the surface of the ground has a uniform side slope of 1 in 10. The width at the formation level is 4.0 m. Determine the volume of excavation between two points 50 m apart on the centerline with the dept of cutting at the first point being 6.0 m and at the second point being 8.0 m, while at a point halfway between them the depth is 6.5 m. If the points at which the depth of cutting is measured lie on a curve of radius 300 m, what will be the correction to be applied?

3. In a railway cutting, the side slopes are 1.5:1 and the surface of the ground has a
uniform side slope of 1 in 10. The width at the formation level is 4.0 m. Determine the
volume of excavation between two points 50 m apart on the centerline with the depth
of cutting at the first point being 6.0 m and at the second point being 8.0 m, while at a
point halfway between them the depth is 6.5 m. If the points at which the depth of
cutting is measured lie on a curve of radius 300 m, what will be the correction to be
applied?
