Calculation steps and methods of earthwork volume for site leveling

1. Draw the grid in proportion within the leveling range of topographic map. The smaller the grid, the more accurate it is. Generally, each grid of uncomplicated terrain is 10m× 10m.

2. Find the elevation of four corners of each square on the topographic map.

3. Subtract the designated site leveling elevation from the average elevation of the four corners, and multiply it by the square area to get the number of squares, which means excavation and filling.

4. Add the positive values of all squares to the total excavation volume and the negative values to the total fill volume.

Earthworks

Earthwork is one of the main projects in building construction, including excavation, filling, transportation, drainage and precipitation of all earth (stone) sides. In civil engineering, earthwork includes: site leveling, subgrade excavation, civil air defense engineering excavation, ground filling, subgrade filling and foundation pit backfilling.

To arrange the construction plan reasonably, try not to arrange it in the rainy season. At the same time, in order to reduce the construction cost of earthwork and implement the principle of not occupying or occupying less cultivated land and being beneficial to land reclamation, it is necessary to formulate a reasonable earthwork allocation plan and make overall arrangements.
