Annual Report: Academician Du Yanliang

Academician Du Yanliang of the Chinese Academy of Engineering first delivered a report on the 2024 annual work summary and the 2025 annual work plan on behalf of the National Key Laboratory of Green and Long - life Road Engineering in Extreme Environments (Shenzhen) at the conference. Academician Du began by introducing the overall construction status of the national key laboratory and the construction progress of its Shenzhen section.

He then provided a detailed account of the team's work in 2024, covering scientific research tasks, platform construction, open - fund projects, team building, and international cooperation and exchange. Focusing on intelligent construction and safe operation and maintenance of transportation infrastructure such as highways and railways, he highlighted the team's significant achievements in several key areas. These included new - type fiber - optic sensing, intelligent perception of structural safety, rapid detection of hidden defects, precise identification and intelligent diagnosis of structural catastrophic failures, space - air - ground intelligent monitoring and collective intelligence perception technologies, intelligent management and dynamic tracking platforms, and key technologies for structural durability assessment and improvement.

Meanwhile, Academician Du summarized the two major characteristics of the team's work in conjunction with the two key tasks undertaken by the national key laboratory:intelligent monitoring and early warning of wide - area hidden catastrophic changes and key technologies for disaster prevention, mitigation, and intelligent operation and maintenance in coastal areas.The first characteristic isthe focus on extreme cold and high - altitude environments to serve the construction and operation of major national projects.The second isthe focus on the safety and operation and maintenance of infrastructure in coastal extreme environments to support the development and construction of the Greater Bay Area.

In conclusion, Academician Du introduced the team's overall work objectives for 2025, as well as key tasks in several areas. These include advancing ongoing projects, actively applying for new projects, serving major national projects, improving institutional construction, building experimental platforms, cultivating talent teams, strengthening international cooperation and exchange, and supporting the development of relevant disciplines.

Following the conclusion of the report, the conference transitioned into the High - End Academic Forum session, where Academician Yue Qingrui, Academician He Chuan, and Master Wang Shuangjie respectively delivered keynote speeches.

Keynote Report 1: Exploration of Monitoring and Early Warning Technologies for Road and Bridge Safety RisksbyAcademician Yue Qingrui

Academician Yue Qingrui introduced his team's exploratory research from three aspects: the challenges faced by road and bridge safety, the "space-air-ground integrated" monitoring and early warning technology, and future challenges and prospects. Academician Yue pointed out that the safety risks of China's roads and bridges have distinct characteristics, including discreteness, suddenness, concealment, and complexity. The tasks of safety monitoring and early warning are heavy, difficult, and highly challenging. Based on the safety needs of roads and bridges, it is necessary to consider establishing a safety management and control system architecture based on the safety "risk source - disaster-bearing body - disaster reduction capacity" theory, and to enhance the level of risk perception, early warning, and response through intelligent means to achieve scientific, precise, and systematic prevention and resolution of road and bridge safety risks.

He then went on to detail the space-air-ground integrated monitoring and early warning system, which consists of "space-based" satellite remote sensing, "air-based" drone inspections, and "ground-based" IoT monitoring. This system aims to achieve high-density, high-precision, and high-timeliness monitoring and early warning across the entire domain, with full information and around the clock, to ensure the safe operation of wide-area roads and bridges and prevent major accidents.

Keynote Report 2: Progress in Intelligent Construction Technology of Tunnel Blasting Method by Academician He Chuan

Academician He Chuan introduced the progress of his team from four aspects: the technical challenges of existing tunnel construction, the history and current status of the tunnel blasting method, the innovation of intelligent construction technology and theory, and their application effects in tunnel projects. Academician He emphasized that the blasting method remains the mainstream approach for constructing large transportation tunnels in complex environments. It is necessary to continue promoting intelligent tunnel construction by integrating mechanization, automation, informatization, and existing technologies. Through comprehensive perception, interconnection, processing, and learning, intelligent decision-making in tunnel construction can be achieved. This includes establishing a technical system that integrates intelligent rock mass classification, intelligent decision-making on construction methods and support systems, and intelligent mechanized equipment for all construction processes, to ensure the quality and safety of tunnel construction. Currently, intelligent machinery and equipment for tunnel blasting have been widely applied in major national projects such as the Sichuan-Tibet Railway, significantly increasing construction speed, reducing construction risks, and achieving remarkable economic benefits.

Keynote Report 3: Experimental Engineering of Highways in Permafrost Regions by Master Wang Shuangjie

Master Wang Shuangjie introduced his team's work on the experimental engineering of highways in permafrost regions from three aspects: the background of the Qinghai-Tibet Highway construction, the implementation plan, and the directions for innovation. He detailed the development of the Qinghai-Tibet Highway since its completion and opening to traffic in 1954, as well as the challenges faced in constructing highways in permafrost regions. He pointed out that the Qinghai-Tibet Highway has made significant contributions to the peaceful liberation, poverty alleviation, and social development of Tibet in different historical periods. However, due to early insufficient understanding of permafrost, the highway faced many problems, leading to multiple reconstruction and remediation efforts.

Master Wang focused on the fourth phase of the remediation work of the Qinghai-Tibet Highway since 2008. He explained the mechanism of permafrost subgrade thaw settlement and how to regulate energy and reduce thaw settlement by reasonably determining the subgrade height and setting up special-structured subgrades. He emphasized that the significant reduction in the disease rate of the Qinghai-Tibet Highway is due to the structural remediation measures taken at various high-thaw-risk sections. These technologies and experiences have provided valuable guidance for constructing highways in permafrost regions in China.

Academician Du Yanliang concluded the session. He expressed his gratitude to all the units for their strong support and meticulous guidance to the laboratory. He stated that the laboratory would continue to work hard and achieve more in the new year. He hoped that under the guidance and support of experts and colleagues, all team members would unite, strive together, and jointly plan for the development of road engineering, contributing to overcoming challenges in extreme environments. The summary was acknowledged by all participants, and the meeting concluded amidst warm applause from the entire audience.
