BIM-based earth and stone volume calculation method, system, equipment and storage medium

Abstract

The present application relates to the field of civil engineering, and in particular to a BIM-based earthwork volume calculation method, system, device and storage medium. The method includes: acquiring original site topography data, where the original site topography data includes three-dimensional coordinates of the original site topography generate the original site three-dimensional surface model according to the original site topographic data; create the site leveling design surface model according to the site leveling design requirements; compare the original site three-dimensional surface model and the site leveling design surface model to obtain the required excavation and backfilling amount of earthwork. This application uses BIM technology to model and compare the original site and site leveling design respectively, which can be graded to the terrain surface according to a certain slope ratio and achieve accurate excavation and filling balance, so as to accurately calculate the earthwork required for excavation and backfilling for site leveling. It can reduce the adjustment operation, display the adjustment results in real time, optimize the design to the maximum extent and achieve the balance of cut and fill.

Description

technical field [0001] The present application relates to the field of civil engineering, in particular to a BIM-based earthwork volume calculation method, system, equipment and storage medium. Background technique [0002] In the process of site leveling, site leveling work such as large-scale excavation and backfilling is often required; the accounting of engineering earthwork is an important work in site leveling engineering, and it is also an important indicator of civil engineering cost accounting. [0003] The relevant domestic calculation method of site earthwork is the square grid method. The basic idea of ​​the square grid method is to divide the site into several squares, and then mark the design elevation in the site and the natural ground elevation respectively on the corners of the grid, and the design elevation of the site. The difference from the natural ground elevation is the construction height of each point. It is customary to use "+" to indicate fill and ...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that it is very cumbersome to calculate the site leveling with the traditional method, because the terrain surface is irregular, and it is very difficult to slope to the terrain surface according to a certain slope ratio and achieve accurate balance of excavation and filling of
