Highway Earthworks Calculator

Calculates cut and fill areas of a section of highway earthworks

Calculates cut and fill areas of a section of highway earthworks.

function [cut,fill]=Earthworks(engl,engll,englr,egl,b,h,s,q,scut)

input:

engl: center elevation of ground
engll: elevation at 50 m left to centerline of ground
englr: elevation at 50 m right to centerline of ground
egl: roadbed elevation
b: roadbed width
h: roadbed height
s: roadbed slope (1 Vertical: s Horizontal)
q: ditch width
scut: cut slope (1 Vertical: scut Horizontal). Depends on soil type

fill slope is defined from bottom as 1:4 for up to 2m, then 1:3 for 2-4 m, 1:2 for 4-6 m then 1:1.75

output:

cut: cut area
fill: fill area

Cross section figure is also plotted with key coordinates located.
