Problems solved by technology

However, the current BIM applications are mainly limited to civil engineering and bridges, and there is still a lack of corresponding components for tunnel BIM
In particular, the BIM-based tunnel multi-information monitoring and control method has not been reported yet.
[0005] The following problems need to be solved to realize the BIM-based tunnel automatic monitoring and control method: (1) Since the current commercial BIM platform lacks the existing tunnel BIM components, how to expand the tunnel sensor BIM component model, and realize the BIM of tunnels and sensors according to different construction conditions; Automated rapid modeling to intuitively express tunnel and sensor models is a key issue
(2) How to automatically collect multivariate monitoring information based on the established BIM model, and realize the association between the properties of BIM components and monitoring data based on tunnel sensors is a difficult point

Embodiment 1

[0108] A BIM-based automatic monitoring and control method is now established for a highway tunnel in the northern region. BIM-based automated modeling. When the monitoring sensor model is established, it is necessary to run the modeling program written in C# language through the secondary development of Revit. The position parameters (radius and angle) of the monitoring sensor model input and placed in the Revit environment can be automatically generated and placed at the specified position. , eliminating the need to search for locations repeatedly during manual modeling. Using Revit secondary development to realize parametric modeling can complete the modeling work efficiently and accurately.

[0109] The programming environment for the secondary development of Revit adopts visual studio2013, and is written in C# language that supports .Net Framework, and the revitAPI.dll and revitAPIUI.dll dynamic link libraries are referenced in the compiler. Install the AddinManager plu...

Abstract

The invention discloses a tunnel engineering automatic monitoring control method based on a BIM technology. The method comprises the following steps of 1, building a tunnel surrounding rock structureassembly and a sensor assembly based on information extension of an IFC standard, building a tunnel BIM model comprising the tunnel surrounding rock structure assembly and the sensor assembly, and enabling the tunnel BIM model to be the same as a tunnel structure of a construction site; 2, acquiring monitoring data information of a sensor arranged in a tunnel on the construction site, and storingthe monitoring data information; and step 3, establishing a mapping relationship between the stored monitoring data information and the sensor component in the tunnel BIM model, and adding the monitoring data information to the tunnel BIM model based on the mapping relationship. According to the method, the relation between monitoring data collected by an on-site sensor and the sensor assembly inthe BIM model is established, monitoring of multiple information of tunnel construction is realized, and the construction safety is ensured.

Description

technical field [0001] The invention relates to the technical field of automatic monitoring of tunnel engineering, in particular to a method for automatic monitoring and control of tunnel engineering based on BIM technology. Background technique [0002] The tunnel construction process is the process of digging in complex geological bodies. Due to the complexity and uncertainty of geological bodies, there is a certain blindness in the pre-design. It is particularly necessary to monitor the information of the tunnel surrounding rock and dynamically adjust the construction based on the monitoring data. This is also the core concept of tunnel information construction and control construction, and has become a mandatory requirement of tunnel construction specifications. [0003] Traditional tunnel construction monitoring is manual, with low monitoring frequency, poor monitoring safety, and monitoring errors are significantly affected by human factors. The monitoring data of th...
