Problems solved by technology

With the continuous progress of the two technologies in recent years, BIM+GIS technology provides good support for the informatization and intelligent development of the construction industry. GIS establishes a spatial database, and BIM refines and supplements it. From the macro and micro Two technologies have been integrated and upgraded with one plus one greater than two from two perspectives, but they have not been used in foundation and foundation subdivision projects, which cannot solve the above problems

specific Embodiment approach

[0029]The purpose of the present invention is to overcome the deficiencies of the prior art, reduce the disputes over the amount of earthwork and rockwork, and adopt BIM+GIS to simulate the calculation technology of earthwork balance. In the early stage of the project, UAV forward and oblique photography technology is used to collect the original terrain data of the project site, and the original data database is formed accurately, low-cost and efficiently, and the data is processed based on the original data database to generate high-precision GIS "topography" In the model, the excavation and backfilling of the earth and stone on site are measured and calculated. At the same time, in order to reduce errors, according to the project geological survey report, Civil 3D is used to establish the "geological model", and according to the project foundation pit support construction drawing and project foundation construction The figure establishes the BIM "pit and foundation" model, a...

Abstract

The invention provides a foundation and foundation division engineering analysis and model selection method based on BIM + GIS, and the method comprises the steps: collecting the topographic data of aproject site, and forming a database; processing the data in the database to generate a GIS terrain model; generating a BIM geological model according to the project geological survey report; determining the form of a foundation pit support and the form of a foundation, and generating a foundation pit and foundation BIM model according to related design drawings; nesting the GIS terrain model andthe BIM geological model, and correcting the surface deviation of the BIM geological model to form a BIM correction model; carrying out secondary nesting on a foundation pit, a foundation BIM modeland a BIM correction model to form a comprehensive model, carrying out rapid in-field measurement on the comprehensive model to calculate the project amount of earth-rock planned excavation and backfill of a project site, and carrying out related analysis and model selection on a foundation and a foundation branch project, so that the cost is effectively controlled.

Description

technical field [0001] The invention relates to a BIM+GIS-based foundation and foundation division engineering analysis and type selection method. Background technique [0002] The foundation and foundation subdivision projects include unsupported earthworks, supported earthworks, foundation treatment subdivision projects, pile foundation and other subdivision projects. Earthwork without support and earthwork with support include earthwork excavation, earthwork backfill, and site leveling. It refers to the calculation of the amount of earth and rock that needs to be excavated at high places in the site. The traditional earth and rock balance calculation method is to use the "square method" to draw a "earth and rock balance map" to calculate the amount of earth and rock that needs to be excavated at high places in the site and the needs of low places. The amount of earthwork for backfilling is the amount of earthwork transported in and out of the plan. The calculation proces...
