Road engineering earthwork volume information processing method and system based on BIM technology

Abstract

The invention discloses a BIM technology-based road engineering earthwork volume information processing method and system, and the method comprises the steps: obtaining the elevation data of each road surface investigation point in a to-be-detected road BIM information model, and obtaining the elevation data of contour lines in the to-be-detected road BIM information model; analyzing and acquiring cross section areas of each higher contour line area and each lower contour line area in the BIM information model of the to-be-detected road, detecting soil parameter data in each higher contour line area and each lower contour line area in the to-be-detected road, and analyzing soil settlement influence coefficients of each higher contour line area and each lower contour line area; according to the method, the actual digging depth of each region higher than the contour line and each region lower than the contour line in the to-be-measured road is analyzed, and the comprehensive estimated earth volume of the to-be-measured road is calculated and displayed, so that the accuracy and scientificity of road engineering earth volume accounting are improved, and the refined cost management level of road engineering is improved.

Description

technical field [0001] The invention relates to the field of road engineering earthwork quantity analysis, and relates to a road engineering earthwork quantity information processing method and system based on BIM technology. Background technique [0002] In road engineering, site leveling work such as digging trenches and filling soil is often required. Among them, the amount of engineering earthwork is an important part of the investment and settlement of road engineering construction, and the accurate calculation of the amount of earthwork in road engineering is of great significance to the budget in the early stage of the project and the settlement in the later stage. [0003] At present, there are some defects in the existing method for calculating the earthwork volume of road engineering: [0004] 1. The existing road engineering earthwork accounting and processing methods basically use manual on-site observation and sampling to obtain engineering terrain data, which ...

Problems solved by technology

[0004] 1. The existing road engineering earthwork accounting and processing methods basically use manual on-site observation and sampling to obtain engineering terrain data, which not only requires a lot of human resources and time costs, but also has the problems of low efficiency and large errors in manual surveys, thereby reducing The accuracy and scientificity of the calculation of earthwork in road engineering has seriously affected the budget and settlement of road engineering;

[0005] 2. In the existing method, the soil condition of the road area is not considered when calculating the earthwork volume of road engineering, which leads to deviations in the calculation of earthwork volume for road engineering, which affects the construction management progress of road engineering, and then affects the cost accounting of road engineering , reduce the level of refined cost management of road engineering;
