Problems solved by technology

During the expert group discussion, it is often difficult to assess the severity of the disease, or even make a wrong judgment, because it is often impossible to go to the scene to watch it and can only explain it through pictures or photos.

[0057] see figure 1 , this embodiment provides a bridge monitoring method, which can monitor the bridge in real time by building a model, which is very convenient. The bridge monitoring method is mainly realized based on the BIM system.

[0058] BIM (Building Information Modeling), which is called Building Information Modeling in Chinese, is based on the relevant information data of construction projects as the basis of the model to establish the building model, and simulate the real information of the building through digital information simulation. It has eight characteristics of information completeness, information relevance, information consistency, visualization, coordination, simulation, optimization and graphing. BIM system is a digital tool applied to engineering design and construction management. It integrates relevant information of various projects through parameter models, and shares and transmits them in the whole life cycle of project planning, operation and mai...

[0076] This embodiment provides a bridge monitoring method, the basic principles and technical effects of which are the same as those of the first embodiment. For a brief description, for parts not mentioned in this embodiment, reference may be made to the corresponding content in the first embodiment.

[0077] This embodiment provides a bridge monitoring method, which specifically includes the following steps:

[0078] S1: Construct the 3D bridge model of the bridge and perfect the 3D bridge model.

[0079] Specifically, in the BIM system, the BIM model of the bridge is directly constructed using the pre-design data or construction data, and then the bridge model is scanned by 3D scanning technology to re-establish the 3D bridge model of the bridge. At the same time, combine the built-in software of the BIM system to improve the 3D bridge model. Specifically, combine the BIM system to set the sensor module on the 3D bridge model, and build modules such as steel bars and prest...

Abstract

The invention provides a bridge monitoring method, and relates to a bridge monitoring technology. The bridge monitoring method comprises the steps that a three-dimensional terrain model is establishedbased on topographic information obtained by aerial photography, the three-dimensional terrain model is integrated with a pre-constructed three-dimensional bridge model in a system, thereby obtaininga three-dimensional scene model, bridge disease information obtained by tour inspection is integrated with the three-dimensional scene model in the system, the bridge disease information is displayedon the three-dimensional scene model to obtain a three-dimensional disease model, and a specific disease type and disease degree of a bridge can be obtained by visually analyzing the three-dimensional disease model; a maintenance scheme can be obtained by analyzing the three-dimensional disease model, thereby greatly reducing the time of the maintenance and scheme designing. Compared with the prior art, the bridge monitoring method has the advantages that a maintenance personnel can be helped to quickly find the disease type and disease degree, the maintenance scheme can be timely given, andthe efficiency of bridge maintenance is greatly improved.

Description

technical field [0001] The invention relates to the technical field of bridge monitoring, in particular to a bridge monitoring method. Background technique [0002] In recent years, with the improvement of infrastructure facilities, a large number of bridges have also emerged. With the development of the economy, there are more and more heavy-duty vehicles, and the overloading range is getting bigger and bigger. Some bridge engineering projects are damaged before the repair or are damaged far before the design period. It is no longer a minority. The reason , overloaded transportation has become the first "killer" of damage to bridges and other road facilities. Bridge road rutting, formation of network cracks, sudden increase of dangerous bridges, etc., are rarely caused by the fatigue strength of vehicle loads. It is caused by overloading. Therefore, the real-time monitoring of bridge health is the top priority of bridge maintenance personnel. [0003] In the prior art, b...
