Embodiment

[0042]figure 1A flow chart of a method embodiment of a large project is planarized by the present invention, as shown, the method of playing the upper planning of large projects is coupled to the BIM model data through the central processing system in the central server, and visualization in the BIM model Display, where the central processing system includes the initial terrain creation module, the virtual selection module, the on-site survey module, the initial planning module, the real scene modeling module, the template management module, the site design module, the design module, the temporary facility module, the cost measurement module , General dressing and effect display module.

[0043](1) Preliminary terrain creation module: In the previous stage of the construction stage, the line coordinate control point is imported in 3D map software (such as Ovi Map, BiGemap, ArcGIS, etc.), determine the line towing and terrain, geological construction model, and obtain the project locati...

Abstract

The invention discloses a large-scale project on-site planning method. The method comprises the following steps: building a preliminary terrain model through employing B M + G S, and building a plurality of site arrangement schemes on the basis of the combination of the preliminary terrain model + a high-definition satellite mixed graph and site survey; an unmanned aerial vehicle oblique photography technology is utilized, a live-action model serves as basic data of project planning, an accurate digital terrain is provided for three-dimensional design, temporary construction scheme design is carried out, and project overall temporary construction function partitioning is planned; three-dimensional visualization is taken as a means, cost control is taken as a main line, selection ratios are carried out from the aspects of technology, organization and traffic demands, and a final planning scheme is determined. The problems that in the background art, large projects, especially mountain projects, are large in temporary building number, large in site construction area, short in temporary construction period, high in environmental protection requirement and the like are solved, and the problems that the advantages and disadvantages of schemes are difficult to distinguish and arrangement schemes are more difficult to find in the earlier stage in a traditional mode of combining on-site exploration with plane layout drawings are solved.

Description

Technical field[0001]The present invention relates to the technical field of project planning methods, in particular, involving a method of playing a large project.Background technique[0002]The planning and design of the construction project is the basis and premise of the project's top construction. Unlike the construction industry, large-scale comprehensive projects, especially the honestop of the mountains, and the gully. Among them, the tunnel engineering has a unique feature of "strip-shaped distribution, limited to natural factors". At the same time, the mountain project is increasingly complex, there is a multi-line long, the safety and civilization construction and environmental protection requirements are high, and the level of refined management Backward problems. The traditional large-scale mountain project is planned, side design, side modification, side construction, limit two-dimensional, static mode, often occurs in temporary land and space utilization rate, on-site i...
