Earthwork Cross-section Area

Written by Jerry Ratzlaff on . Posted in Civil Engineering

Earthwork cross-section area can be for small or large areas.

Earthwork Cross-Section Area formula

 $$\large{ A_c = \frac{ 1 }{ 2 } \; \sum_{i = 1}^n \; x \; \left( y_{i + 1} \;-\; y_{i - 1} \right) }$$

Where:

$$\large{ A_c }$$ = area cross-section

$$\large{ x_i }$$ = horizontal axis

$$\large{ y_i }$$ = vertical axis

$$\large{ n }$$ = number of points on cross-section
