BIM-based bridge inspection information management method and system

Abstract

The invention discloses a BIM-based bridge inspection information management method and system. The system comprises a non-destructive inspection module, a dynamic and static load testing module, a damage information BIM module, a detection vehicle information BIM module, a sensor information BIM module, a model intelligent conversion module, a technical condition evaluation module and a loading capacity state evaluation module. According to the system, the standardized recording and integrated management of various types of inspection information can be realized; the inspection information isconverted into three-dimensional visual information by virtue of a BIM technique, so that the visual expression of the inspection information is realized; and by converting a model, processing actualmeasurement information and calculating a theoretical value, the intelligent evaluation on multiple aspects of the technical condition, the loading capacity and the like of bridges is realized. According to the system, the defects that the information is fragmentized, the recording is nonstandard, the expression is not visual, the evaluation is asynchronous, and the like in traditional bridge inspection information management can be improved, and great convenience is provided for the bridge information management works.

Description

technical field [0001] The invention relates to the field of structural safety detection, in particular to a BIM-based bridge detection information management method and system. Background technique [0002] The cost of the bridge structure is high, and the service life is long. During its service period of tens or even hundreds of years, the coupling effects of environmental corrosion, material aging, long-term effects of dynamic and static loads, fatigue effects, and mutation effects, etc. It will inevitably lead to structural damage accumulation and resistance attenuation, and even catastrophic accidents in extreme cases. According to the latest statistics of the transportation industry, there are 779,200 road bridges in my country, and small and medium bridges account for nearly 90%. After the large-scale bridge construction, the operation and management of the bridge followed. The bridge inspection aimed at ensuring the safety of the bridge during its service period i...

Problems solved by technology

[0003]The traditional bridge inspection information management method mainly uses manual inspection as the approach, subjective judgment as the basis, and inspection report as the carrier, resulting in the existing bridge inspection information There are many flaws in management

Mainly include: 1) Fragmentation of information, the information correlation of text, tables, and images in the same test report is weak, and it is difficult to automatically form effective dynamic analysis for multiple test reports at different test time points; 2) Records are not standardized , the detection is mostly recorded after the subjective judgment of the inspectors, and too much depends on the personal qualities of the inspectors. If the standards are not strict and uniform, it is easy to cause blurred, missing or serious deviations in the recorded information; 3) The expression is not intuitive, and one-dimensional text is used Or the detection information described by two-dimensional images, it is difficult to accurately reproduce the real state after information feedback; 4) Synchronous evaluation cannot be achieved, and after simple recording of multi-type detection information, there is still a large amount of follow-up work for information summary and comprehensive analysis
