Recently, the results of the China Railway Construction Science and Technology Award were announced. The scientific research project "Key Construction Technologies and Applications for High - Geostress, Water - Rich and Large - Deformation Tunnels", jointly completed by Yancheng Institute of Technology, China Railway 25th Bureau Group Co., Ltd., Xi'an University of Architecture and Technology and other units, won the "China Railway Construction Science and Technology First - Class Award". Dr. Cheng Yun from the School of Civil Engineering of our university, as a main contributor, made important contributions to this project. It is reported that in 2024, the China Railway Construction Science and Technology Award was granted to a total of 91 projects, including 4 special - class awards, 32 first - class awards, and 55 second - class awards. The awarded achievements cover cutting - edge technologies such as shield tunnels, intelligent construction, and ecological environmental protection.
This project is based on the major strategic needs of the country. Aiming at the construction characteristics and technical difficulties of high -speed railway tunnels in Southwest China, it has systematically and thoroughly studied the deformation mechanism and key control technologies for the construction of high - geostress, water - rich and large - deformation tunnels. It has established a classification standard for large - deformation surrounding rocks in high - geostress and water - rich tunnels, and developed the "construction control technology with reserved large - core soil and micro - three - step bench". A new type of constant - resistance energy - absorbing bolt suitable for high - geostress soft - rock large - deformation tunnels has been developed, and the support technology with constant - resistance energy - absorbing bolts for severely and extremely severely high - geostress large - deformation tunnels has been proposed. The comprehensive construction technology of "full - ring grouting for water control + partitioned bench excavation + grouting reinforcement and strengthening" for the transition from inclined shafts to main tunnels has been developed. The research results have been successfully applied in key projects such as Songpan Tunnel and Hongqiaoguan Tunnel of the Chengdu - Lanzhou Railway, achieving huge economic, social, and environmental benefits.
With the support of relevant departments such as the Science and Technology Department of the university, the School of Civil Engineering adheres to the principle of fostering virtue through education. Taking discipline construction as the leading factor, it strengthens connotative construction and refines research directions. Relying on the national first - class undergraduate major in civil engineering, provincial key disciplines, and the Jiangsu Provincial Engineering Center platform, it promotes the application of scientific research achievements in major national engineering construction, improves the level of discipline construction, and serves local economic development and the high - quality development of the university.
China Railway Construction Science and Technology Award is a science and technology award activity that has been approved, registered, and filed by the National Office for Science and Technology Award Work. It is open to the whole society and is an important award established by social forces in China. This provincial - ministerial - level science and technology award is established by China Railway Construction Corporation Limited. It aims to reward individuals and units that have made outstanding contributions to scientific and technological progress in fields such as railways, urban rail transit, and tunnel engineering. This award covers fields such as engineering technology innovation, equipment research and development, and construction techniques. It is evaluated by an expert committee and has three levels: special - class award, first - class award, and second - class award. Since its establishment, this award has continuously promoted technological innovation in the industry, helped enterprises move towards world - class modern enterprises, and provided support for the "Science and Technology Rejuvenating the Country" strategy.
