Hub dam type comparison and selection scheme quantitative evaluation method and device based on BIM

Abstract

The invention relates to a hub dam type comparison and selection scheme quantitative evaluation method and device based on BIM, and the method comprises the steps: obtaining the related information ofa to-be-compared and selected engineering scheme, carrying out the display of 3D large-scene visual information through employing a BIM information model and a WebGIS platform, carrying out the parametric positioning, and carrying out the Boolean operation; obtaining the score of the related information of the to-be-compared engineering scheme by each scoring person, the proportion of the relatedinformation and the information of each scoring person; carrying out statistical calculation according to the scores of the scoring persons on the subitems of the different hub dam type comparison and selection schemes, and calculating the final score of each hub dam type comparison and selection scheme; the scheme having the highest score being the optimal hub dam type scheme. The method is standard in system, visual, convenient and high in operability, greatly improves the efficiency of determining the hub dam type scheme in the researchable design stage, saves the time cost, and can ensurethat various requirements of water conservancy and hydropower engineering construction are met.

Description

technical field [0001] The invention relates to the technical field of pivot engineering, in particular to a BIM-based quantitative evaluation method and device for pivot dam type comparison and selection schemes. Background technique [0002] With the rapid development of my country's water conservancy and hydropower projects and the continuous improvement of engineering construction levels, water conservancy and hydropower projects can be constructed under narrower and more complex terrain conditions. Engineering problems of optimal hub layout scheme. The determination of the hub layout plan will inevitably affect the safety, economy, construction, operation and other aspects of the entire hub. Therefore, how to evaluate and select the optimal hub layout scheme has become a necessary link and hot engineering issue in the feasibility study and design process of water conservancy and hydropower projects. A reasonable hub layout scheme can not only shorten the construction pe...

Problems solved by technology

[0004] First, the workload is huge and there is repetitive work: the traditional method needs to design several sets of feasible plans according to the design institute, and evaluate the specific information such as the engineering quantity and cost calculated by the design institute. The workload is very huge, and there are some contents The problem of repeated comparison and selection delays the time of the feasibility study stage;

[0005] Second, it is relatively general and there is no established system: due to the many factors influencing the determination of the hub dam type scheme, when evaluating the hub dam type scheme, the traditional method only analyzes the advantages and disadvantages of relevant information, and there is no established evaluation method system, which will lead to The evaluation results are not comprehensive enough and reliable;

[0006] Third, it is easily affected by individual subjective judgments: due to the lack of quantitative evaluation indicators in traditional methods, under the conditions of many influencing factors, subjective judgment is the main way to determine whether a certain program is feasible and its advantages and disadvantages. Under such circumstances, the evaluation results are prone to large deviations due to subjective judgment errors;

[0007] Fourth, the evaluation and analysis process is not intuitive enough: the evaluation process of traditional methods relies more on textual survey data and two-dimensional drawings, and the evaluation and analysis process of hub dam schemes is not intuitive and clear, and the degree of integration with natural geographic information is not high , leading to incomplete evaluation results;

[0008] To sum up, there are many defects in the current traditional evaluation methods for comparison and selection of pivot dam types, and a scientific, reasonable, practical and effective evaluation method for comparison and selection of pivot dam types is urgently needed
