Nowadays we have to handle the tasks for volume determination of surge pile materials (sand, coal, crushed stone) on industrial objects and building grounds. The type of work is necessary for keeping record of supplied and consumed materials, and also for their piling. This article gives com-parative analysis of 3 calculation methods for land works (horizontal sections, cone, vertical parallel section) in AutoCADCivil 3D.
The object of research was the sand, delivered and piled in the Novosibirsk river port. The sand is a rather difficult substance to be calculated as it gets settled down in wet condition and blown away in dry one.
The results of the research showed that the most accurate method for sand volume calculation is vertical parallel section one in AutoCADCivil 3D.
