Embodiment Construction

[0029] The following is based on Figure 1 to Figure 3 The specific embodiment of the present invention is further described, in order to make the present invention clearer, the present embodiment is described with a cable-stayed bridge:

[0030] An INVENTOR-based structural hierarchical modeling method for bridge management and maintenance process, including the following steps:

[0031] Step 1: According to the bridge maintenance management requirements and referring to the bridge maintenance specification, carry out structural hierarchical division of the objects to be modeled, and build a bridge structure tree from top to bottom as a reference for the modeling catalog; the bridge structure tree can refer to the long The maintenance of large bridges is classified into uplink and downlink, number of spans, substructure, component type, component type and component, and uplink and downlink, number of spans, substructure, component type, component type and component are the di...

Abstract

The invention discloses an INVENTOR-based structural hierarchical modeling method for bridge tube maintenance process, which comprises the following steps of: carrying out structural hierarchical division on an object to be modeled, and establishing a bridge structural tree from top to bottom; according to the bridge structure tree, the bottom members of the bridge being built from the lowest level; according to the content of the penultimate level in the bridge structure tree, loading the bottom layer. Ipt file and assembling it to build all the models of the penultimate level in the bridge structure tree; all the models of the bridge structure tree being built from bottom to top; checkng the established model to adjust the hierarchy for artifacts that are not hierarchically modeled and artifacts that are incorrectly hierarchically modeled, and finally exporting the IFC format file. The method enables each level component in the BIM model to be disassembled separately, each level component to carry respective related information separately, and integrates the whole bridge model, which not only solves the needs of multi-level evaluation of bridge maintenance management, but also reduces the workload and saves manpower and material resources.

Description

technical field [0001] The invention belongs to the field of BIM application in the bridge management and maintenance phase, and in particular relates to an INVENTOR-based structural hierarchical modeling method for the bridge management and maintenance process. Background technique [0002] Due to factors such as large investment in bridge engineering, complex construction process, long service life, harsh working environment, and unimaginable consequences in the event of risks, the application of BIM (Building Information Modeling) technology in the field of bridges is increasing rapidly, especially in the design and construction stages. , and less used in the custody stage. [0003] The necessary condition for using BIM technology in the stage of bridge management and maintenance operation and maintenance is to establish a BIM model that meets the needs of management, maintenance, operation and maintenance. Bridges built by software such as traditional Revit cannot meet ...
