This project belongs to the field of civil engineering construction. China has already operated 17,738 highway tunnels, ranking first in the world; more than 80% of the tunnels are damaged or leaking water to varying degrees, posing a serious threat to operational safety; with "large scale and numerous diseases," how to achieve rapid and accurate perception of the structural service state has become the primary challenge facing operational safety. The project team, supported by national and provincial-level science and technology projects, has spent over a decade tackling the problem. They have broken through the core key technologies of rapid inspection, real-time monitoring, and detailed diagnosis for highway tunnels, invented full cross-section rapid detection equipment and disease visualization monitoring equipment, and developed a "multi-source integrated" analysis platform. This has achieved rapid and accurate perception of the structural service state, with the following results: 1. Invention of highway tunnel infrared imaging full cross-section rapid detection equipment, overcoming the industry problem of rapid inspection in service status. In response to bottlenecks such as uninterrupted supplementary lighting for one-time travel detection across the entire section, high-frequency synchronous acquisition and storage of images, and precise localization and identification of diseases, a high-density infrared LED packaging method was invented, and a high-power low thermal resistance infrared supplementary lighting device was developed to ensure the required light intensity and uniformity for long-distance imaging in complex tunnel environments; an nanosecond camera array synchronization control system and a gigabit image real-time encoding system were researched and developed; a multi-level precise positioning model based on circumferential laser scanning, longitudinal encoder positioning, and image feature calibration was established, and a method for rapid screening and high-precision identification of diseases was proposed, with crack width recognition accuracy reaching 0.1mm. The equipment achieves rapid detection of tunnel cracks, seepage water, peeling, and contour at speeds up to 80km/h. 2. Invention of tunnel disease visualization monitoring equipment, Real-time monitoring of key areas has been achieved. In response to the limited real-time monitoring methods for tunnel deformation and the difficulty in synchronously monitoring different diseases, a multi-scale adaptive template hierarchical matching algorithm with precise identification of measurement points was proposed, establishing a real-time online monitoring method for tunnel deformation based on zoomed images, with an accuracy of 1mm; integrated disease image recognition algorithms, and developed synchronous visualization video monitoring devices for deformation, cracks, seepage, etc.; proposed an automatic noise reduction method for massive data based on a dynamic coefficient exponential smoothing model and a time-division compensation mechanism, establishing long-term monitoring technical standards for tunnel structures. The achievements have been adopted by two industry standards. Third, research and development of 'multi-source integration' analysis technology and platform were carried out, solving the problem of lack of refined diagnostic technology support for the service state of tunnel structures. To quantitatively evaluate the impact of diseases on the service performance of structures, A tunnel structure disease mechanics analysis model and a structural force response reverse analysis method based on an improved adaptive genetic algorithm have been proposed, and Tongji Shuguang three-dimensional numerical analysis software has been independently developed. A structured fusion standard for 'multi-source' data such as surrounding rock, structure, diseases, and time has been established, and a digital model-numerical calculation seamless docking 'integrated' analysis technology has been proposed. An integrated research and development platform for the service state diagnosis of tunnel structures has been integrated, achieving refined analysis and evaluation of the service state. The achievements have been adopted by the industry standard 'Technical Specification for Reinforcement of Highway Tunnels'. 33 invention patents, 5 utility model patents, and 25 software copyright licenses have been authorized, participated in compiling 3 industry standards, published 5 monographs, and published 67 papers (49 of which are included in SCI and EI), with a total of 822 citations. The achievements have been used for inspection and diagnosis of tunnels in 19 provinces across the country, totaling 1,569 tunnels with a combined length of 3,200 km, generating an economic benefit of 380 million yuan over the past three years. Renowned academicians and experts have assessed that "the integrated invention of environmentally friendly full-section detection equipment using infrared light source imaging has achieved high-precision, non-interference rapid detection, which is a world first; the overall achievement meets international advanced standards, with the highway tunnel infrared imaging full-section rapid detection equipment and its crack width recognition accuracy indicators leading internationally." Multiple testing units unanimously agree that this invention "can achieve full-section, zero-interference rapid detection of highway tunnels."
