Method for calculating quantity of excavation and filling projects based on Bentley software

Abstract

The invention discloses a method for calculating the quantity of excavation and filling projects based on Bentley software. In mine engineering, water conservancy and hydropower engineering, landslide squaring treatment engineering and other construction engineering projects involving a large amount of earthwork, the earthwork excavation amount often needs to be accurately calculated. A traditional grid method is only suitable for calculating flat and regular sites. The method comprises the following steps of: importing contour lines and elevation point data of a plane graph precisely measured by CAD into Bentley software to obtain volume information of a three-dimensional cutting body and a three-dimensional filling body, wherein the volume of the three-dimensional cutting body is the number of projects calculated by excavation earthwork, the volume of the three-dimensional filling body is the number of projects calculated by filling earthwork. The method is particularly suitable for engineering projects with varied cutting slope, special-shaped cutting surface, fluctuating original terrain surface and large and irregular local terrain jump of the excavation surface, overcomes calculation errors and limitation of a traditional calculation method, and improves the calculation precision and efficiency.

Description

technical field [0001] The invention belongs to the technical field of road engineering, in particular to a method for calculating the quantity of cut and fill works based on Bentley software. Background technique [0002] In mining projects, water conservancy and hydropower projects, landslide brushing control projects and other construction projects involving a large amount of earthwork, it is often necessary to accurately calculate the amount of earthwork excavated. The traditional grid method is suitable for calculating the amount of earthwork that has a flat and regular site; the original ground has little undulations and the terrain gradually changes; however, the actual excavation project excavation surface has variable slopes and irregular shapes; , The local terrain is characterized by large jumps and irregularities, and the traditional calculation method has certain errors and limitations. [0003] Bentley software realizes the WYSIWYG three-dimensional calculatio...
