The Kickoff Meeting for the Consulting and Evaluation Project launched by the Academic Divisions of the Chinese Academy of Sciences for solving the "Key Scientific and Technical Issues of Sichuan-Tibet Railway Rock Mass Engineering", namely the 2nd

In order to better support the major national projects, and effectively solve the complex scientific problems and engineering technical problems encountered in the construction of the Sichuan-Tibet Railway, the kickoff meeting for the consulting and evaluation project launched by the Academic Divisions of the Chinese Academy of Sciences for solving the "Key Scientific and Technical Issues of Sichuan-Tibet Railway Rock Mass Engineering", namely the 2nd "Yalin Forum" sponsored by the CSRME and organized by China Railway Construction Corporation and the State Key Laboratory for GeoMechanics and Deep Underground Engineering, was successfully held online and offline on November 16, 2021. The kickoff meeting was hosted by Academician Shen Changyu, Deputy Director of the Division of Technological Sciences, the Chinese Academy of Sciences.

Academician He Manchao, the consulting and evaluation project leader for the "Key Scientific and Technical Issues of Sichuan-Tibet Railway Rock Mass Engineering" and the president of the CSRME, was the convener of this "Yalin Forum". 18 academicians presented at the meeting, including Academician Yang Wei, Academician He Yaling (Deputy Director), Academician Wang Guangqian, Academician Yu Qifeng, Academician Zhai Wanming; the experts from Sichuan-Tibet Railway engineering design, construction, and management include: Researcher Yin Yueping, Researcher Zhao Guotang, Mr. Wang Jiansheng, Executive Deputy Director of the National Sichuan-Tibet Railway Technology Innovation Center. In addition, there are still 386 engineering technicians participated in this forum, including lab associates of the National Natural Science Foundation of China's major projects, representatives of the "National Major Projects-State Key Laboratory" Science and Technology Innovation Consortium, engineering and technical personnel from China Railway Construction, China Railway First Survey and Design Institute, China Railway 11th Bureau, China Railway 12th Bureau , China Railway 18th Bureau total.

The forum lasted for 1 day only, 12 academic reports, including 2 invited reports, 5 project reports, and 5 expert reports. Professor Yu Qifeng, Academician of the Chinese Academy of Sciences, gave an invited report titled "Sub-millimeter-level static and dynamic multi-point displacement monitoring technology and system for large-scale engineering structures", and Professor-level senior engineer Zhao Guotang from China National Railway Group made an invited report titled "Digital Construction Technology and Application in Railway Engineering" He Manchao, Academician of the Chinese Academy of Sciences, made a report titled "Mechanism, prevention measures, and control methods for disasters in the Sichuan-Tibet Railway Deep-Buried Super-long Tunnel Engineering", and researcher Zhou Hui from the Institute of Rock and Soil Mechanics, Chinese Academy of Sciences, made a report titled "Fault Dislocation Mechanism and Control", Professor Liu Quansheng from Wuhan University gave a report titled "Large Deformation Control Technologies for Soft Rock Tunnel with High Ground Stress", Professor Tang Chunan from Dalian University of Technology gave a report titled "Hard-Roof Rock Burst Mechanism and Control", Professor He Maogang from Xi'an Jiaotong University gave a report titled "Mechanism and Prevention of High Temperature and High Humidity". In the process of comment, the experts commented on the above reports one by one and were very active in the speeches and discussions. Everyone was very excited and interested in the exchange of academic views.

Academician He Manchao, President of the CSRME, in the afternoon presided over the meeting, and a total of 5 reports were delivered. Zhao Yong, commander of the Tibet Headquarters of Sichuan-Tibet Railway Construction, gave a report titled "Progress of Sichuan-Tibet Railway Engineering Construction and Key Scientific and Technical Issues", and Chief Engineer Yang Guozhu from the Sichuan-Tibet Railway Headquarters of China Railway Construction gave a report titled "Main Technical Difficulties and Thoughts in Sichuan-Tibet Railway Tunnel Construction", Survey Master Li Guoliang from China Railway First Survey and Design Institute made a report titled "Achievements and Challenges in Railway Tunnel Construction in Western Regions", and Chief Engineer Yang Tielun from Gansu Changda Company made a report titled " NPR Anchor Cable Control Technology and Engineering Application for Large Deformation of Soft Rock in Muzhailing Expressway Tunnel", and Deputy General Manager Han Yu from Guangxi Road and Bridge Group, gave a report titled " NPR Anchor Cable Control Field Test for Large Deformation of Soft Rock in Yunnan Changning Tunnel".

Relying on the consulting project launched by the Academic Divisions of the Chinese Academy of Sciences, this forum focused on key core technological breakthroughs, and called on scientific and technological workers to carry forward the spirit of "two roads" and the spirit of Qinghai-Tibet Railway, and timely applied scientific and technological achievements to the construction of Sichuan-Tibet Railway, provided with suggestions on "Scientific construction, safety construction, green construction, high-quality promotion of engineering construction". The forum builds a platform for the connection of technological innovation and engineering in the construction of the Sichuan-Tibet railway, further condenses the cooperation consensus of the scientific workers and railway builders, and makes new contributions to the comprehensive construction of a modern socialist country.
