Bridge assembly risk model construction method and system based on BIM

Abstract

The invention discloses a BIM-based bridge assembly risk model construction method and system, and relates to the field of bridge assembly. The method comprises the following steps that modular decomposition is conducted on a bridge structure, a construction mode and a construction stage; control parameters and structural relations of all the structures are determined, and parameterized models of the bridge structure, the construction mode and the construction stage are preliminarily established; debugging the parameterized model, and constructing a parameter library; and creating a BIM risk source management system according to the parameter library, and establishing a risk source information model. On the basis of a traditional risk management and control theory, real-time dynamic assessment and early warning of security risks can be realized.

Description

technical field [0001] The invention relates to the field of bridge assembly, in particular to a BIM-based method and system for building a bridge assembly risk model. Background technique [0002] The core of BIM is to establish a virtual three-dimensional model of construction engineering and use digital technology to provide a complete and actual construction engineering information database for this model. The information base not only contains the geometric information, professional attributes and state information describing building components, but also contains the state information of non-component objects (such as space and motion behavior). With the help of this three-dimensional model containing construction engineering information, the information integration degree of construction engineering is greatly improved, thereby providing a platform for the exchange and sharing of engineering information for stakeholders of construction projects.

AI Technical Summary

Problems solved by technology

[0003] At present, BIM technology is mainly based on manual modeling in the modeling of railway bridges. However, when the bridge structure is complex and the design needs to be revised repeatedly, the drawbacks of manual modeling, such as low modeling efficiency and low modeling accuracy, are becoming more and more obvious.

Among them, the research on the basic theory of risk management and control has been relatively complete. What is lacking is how to ensure the effective operation of the risk management and control system through intelligent means, that is, to realize real-time dynamic assessment of safety risks and early warning, and effective implementation of risk management and control measures.
