“…Concrete bridge has always been the main type of bridges. In recent years, the research focus of concrete bridge has gradually shifted to the operation management and maintenance (Zhou and Zhang 2019). At the beginning of 2019, Gao et al (2019) pointed out that it is of great importance to study the structural durability, the whole life cycle design, and the combined environmental effects of the bridge structures in China.…”

“…From reform and opening up to now, along with the rapid development of national science and technology, China's bridge industry has undergone three stages (i.e., learning and following in the 1980s, tracking and improving in the 1990s, and innovating and transcending since the start of the twenty-first century), and completed the transition from "follower" to "competitor," and finally to "leader." (Zhou and Zhang 2019). In this section, the achievements, characteristics, and challenges of the bridge industry in China will be presented.…”

“…Due to the great efforts of Chinese researchers and engineers, a great number of technical problems in materials, design, construction and management have been solved. Highperformance materials, such as C50 and C60 concretes, Q500 steel, and 2000 MPa steel wire, have been applied in real bridges (Zhou and Zhang 2019). Rational design methods and effective vibration control technologies have been proposed for cable-stayed bridges, suspension bridges, arch bridges, and beam-like bridges.…”

“…Among them, there are many extra-long, extremely complex and world-renowned bridges with major challenges, such as the Hong Kong-Zhuhai-Macao Bridge, the Su Tong Yangtze River Highway Bridge, the Ma'anshan Yangtze River Highway Bridge, and the Hangzhou Bay Bridge. Considering the world's top 10 main span bridges of different types, the number of bridges owned by China is shown in Table 1 (Zhou and Zhang 2019). For each type of bridge, over half of them are in China.…”

Bridge health monitoring (BHM) technology has been widely accepted as a powerful tool to assess structural performance and has moved from research to practice. Driven by the enormous demand of ensuring bridge safety, the application of BHM technology is particularly active in China and has become an emerging industry in the civil engineering community. It is a common belief among civil engineers that the development and implementation of industry standards will be of paramount importance in guiding the healthy development of BHM and increasing the transfer of professional knowledge and techniques to practical applications. This paper presents a comprehensive overview of the standardization construction and development trend for BHM in China. The achievements, characteristics, and challenges of China’s bridge construction are first introduced. Then, the existing problems of BHM and the necessity of constructing the standardization system for the BHM industry are discussed. Following that, these standards published for guiding BHM system design, construction, management, and maintenance, especially sensor selection, sensor placement, sensor installation, data transmission, data storage, data processing, and early warning, are outlined. Finally, work requiring further efforts in the near future is drawn.

“…With the birth and rise of a new round of scientific and technological revolution and industrial change, modern technologies such as "5G" technology, "Internet +" technology, new sensors, robots and artificial intelligence have brought new opportunities to the innovation of bridge engineering [ 5 ], and bridge inspection is developing towards automation and intelligence [ 6 ]. Karim et al [ 7 ] and Aliyari et al [ 8 ] proposed to replace labor-intensive bridge detection with UAV mobile camera, and also proposed a structural damage pattern recognition algorithm based on cellular automata.…”

China is shifting from the stage of large-scale bridge construction to the stage of equal emphasis on the construction and maintenance of bridges. The problems of low efficiency and high cost in bridge inspection are becoming more and more prominent, which threaten people’s life safety. In this paper, the deterioration state prediction model of concrete beam bridge under Boosting DT C5.0 was established as the basis, and optimization suggestions were put forward in terms of bridge inspection standards and processes, which aims to perfect the bridge inspection mechanism, realize the fine management of the bridge and prolong the service life of the bridge. Research shows that: first, the bridge inspection standard with a single index should be improved into the bridge inspection standard with multiple indexes, so as to scientifically determine the bridges that need to be inspected and optimize the allocation of maintenance resources. Second, the bridge deterioration state prediction model is used to add a screening mechanism for the bridge in the inspection plan, which can effectively reduce the workload of bridge inspection and enhance the inspection efficiency. Third, the deterioration phenomenon of coexistence between adjacent traffic assets should be fully considered and the linkage inspection mechanism of adjacent traffic assets should be established to improve the effect of bridge inspection.
