The invention relates to the field of civil engineering, in particular to a BIM (Building Information Modeling)-based earth-rock volume calculation method, system and device and a storage medium, the method comprises the following steps: acquiring original site topographic data, the original site topographic data comprising three-dimensional coordinate data of original site topography; generating a three-dimensional curved surface model of the original site according to the topographic data of the original site; creating a site leveling design curved surface model according to site leveling design requirements; and comparing the original site three-dimensional curved surface model with the site leveling design curved surface model to obtain the earth and rock volume required to be excavated and backfilled. The original site and site leveling design are modeled and compared through the BIM technology, the slope can be made to the terrain curved surface according to a certain slope ratio, accurate digging and filling balance is achieved, and therefore the amount of earth and rocks needing to be dug and backfilled for site leveling is accurately calculated, adjusting operation is reduced, the adjusting result is displayed in real time, and the working efficiency is improved. The design is optimized to the maximum extent, and digging and filling balance is achieved.
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 ...
