Earthwork Cross Section Volume Calculator
This calculator estimates the volume of earthwork based on the average of two cross-sectional areas and the length between them. It’s commonly used in civil engineering and roadwork projects to determine how much soil needs to be cut or filled.
Calculate Earthwork Volume from Cross Sections
Earthwork Volume (Average End Area) Formula
$$V = \frac{(A_1 + A_2) \cdot L}{2}$$
Where:
- $$A1$$ — area of the first cross section
- $$A2$$ — area of the second cross section
- $$L$$ — length (distance) between the cross sections
- $$V$$ — earthwork volume
This formula, known as the Average End Area Method, is widely used for preliminary earthwork volume estimation. It provides a reliable approximation by averaging the two end areas and multiplying by the distance. Applicable in construction site grading, road embankments, canal excavation, and other linear earthworks.
