It initiated the ecological restoration technology of "Desertification" and carried out pilot tests in Inner Mongolia, Xinjiang and Xisha Islands and reefs, making mechanical desertification control a reality. The team that uses "black technology" to control desertification comes from Chongqing, which has no desert, and from Chongqing Jiaotong University, which is famous for building bridges and roads. Behind the seemingly "no business" is the exploration of the cross innovation of mechanics and ecology. Recently, the leader of the research team, Professor Yi Zhijian, vice president of Chongqing Jiaotong University, was rated as the "most beautiful scientific and technological worker in China" in 2021. Based on its own discipline and specialty characteristics and the basic advantages of scientific and technological innovation, Chongqing Jiaotong University has accelerated the optimization of discipline structure and the transformation and upgrading of scientific research direction, and walked out of the characteristic road of promoting the University's scientific and technological innovation and serving the national strategy and local economic and social development. Keeping pace with the times, interdisciplinary cooperation helps scientific research transformation and upgrading "You may walk along the Sichuan Tibet highway and be attracted by the steep and beautiful scenery along the road, but you may not know that our school was born because of the Sichuan Tibet highway." Tang Boming, deputy secretary of the Party committee and President of Chongqing Jiaotong University, tells freshmen the history of the school in the "first lesson of the school" every year at the beginning of the school season, in order to make students remember their responsibilities and inherit and carry forward the "two-way spirit", Willing to be a "paving stone" to serve national and local needs. From providing technical support for the construction of Sichuan Tibet highway to applying the research results to the construction of many important trunk highways in Southwest China; From Chengdu Chongqing Expressway, the first road in Southwest China, to a number of the world's largest bridge and tunnel projects, such as the largest span arch bridge, the largest span beam bridge and the largest span stone arch bridge in the world; From the Three Gorges Dam to the Hong Kong Zhuhai Macao Bridge; From the smooth regulation of the "golden waterway" of the Yangtze River to the river and sea access of the new land and sea channel in the west, Chongqing Jiaotong University has paid silently. In the last two World University Students' bridge design competitions, the students of the University won the first prize twice in a row. The works are not only exquisite in design, but also full of beauty. "We always keep pace with the times for the development of disciplines." Tang Boming said that more than ten years ago, the school began to explore the teaching of "transportation + art" to increase students' aesthetic literacy, hoping that the major projects they participated in will become classics. In February this year, the "integrated technology for rapid ecological restoration of desertification soil" project of Yi Zhijian's team won the first prize of innovation achievements of China's industry university research cooperation in 2020. This technology is an interdisciplinary subversive innovative achievement of desert ecological restoration studied by the research team of the University from the perspective of mechanics. 20000 mu experimental demonstration projects have been carried out in Inner Mongolia, Xinjiang, Sichuan and other provinces (regions), as well as countries in the Middle East and Africa. "In recent years, on the basis of continuously strengthening and expanding the traditional advantageous disciplines such as transportation, civil engineering, water transportation and economic management, the university has actively carried out the interdisciplinary and upgrading actions of transportation + big data, artificial intelligence and ecological environmental protection, as well as the transformation and upgrading of scientific research direction." Zhou Jianting, vice president in charge of scientific research, introduced that the university is currently engaged in transportation + big data intelligence, big ecology, new materials In the direction of advanced manufacturing and intelligent construction, a number of scientific and technological innovation teams led by academicians have been formed, the discipline layout has been further optimized, and the discipline of "Engineering" has entered the top 1% of Esi's global disciplines, gradually forming a complete discipline and professional system of "water, land, air and rail". The scientific and technological achievements of tackling key technologies have changed from the pursuit of quantity to the pursuit of quality In March 2020, Chongqing Jiaotong University invested 250 million yuan to build the State Key Laboratory of mountain bridge and tunnel engineering covering an area of 250 mu, which was approved to be officially put into operation. The laboratory has independently developed the internationally leading bridge structure environment coupling test platform, long-span arch bridge construction, operation and maintenance comprehensive test platform and tunnel engineering test platform. Its research achievements in the field of long-span arch bridge and extra long tunnel have won 10 first and second prizes of national scientific and technological progress. The university has invested 230 million yuan to build a 300 mu National Inland Waterway Regulation Engineering Technology Research Center, which has undertaken more than 70% of the waterway tests in the Yangtze River and Pearl River basins. It is in the first echelon of inland waterway research in the world, and has built a new Sanxia waterway research base including a 1:100 physical model from Gezhouba to the Three Gorges dam, Technical difficulties in navigation and ship lock construction of the Three Gorges water control project have been overcome. Through the construction of three national key scientific research platforms: the State Key Laboratory of mountain bridge and tunnel engineering, the national inland waterway regulation engineering technology research center and the national local joint Engineering Laboratory of transportation civil engineering materials, Chongqing Jiaotong University gathers and integrates scientific and technological innovation resources inside and outside the University, and carries out key scientific research projects around the national strategic needs, We have broken through a number of technical problems restricting the traffic construction, operation management and green development in western mountainous areas, and achieved a number of leading innovative achievements at home and abroad in the fields of long-span arch bridges in mountainous areas, inland ecological waterways, urban monorail equipment and inland sea access in Western China. In recent years, Chongqing Jiaotong University has actively served the national strategy, built a scientific and technological innovation platform, promoted the transformation and application of achievements, and actively served the national economic construction and social development; Focusing on the strategic goal of building a strong transportation country, it has successively put forward political consultation suggestions such as the construction of a new water transportation channel in the Three Gorges, accelerating the construction of China Myanmar oil pipeline, and improving the construction of Chongqing Yunnan Myanmar Indian Ocean logistics channel, which have been adopted by the general Office of the CPC Central Committee, especially the Chongqing New Europe China Europe train, north-south channel initiative and other achievements to reduce costs and increase efficiency for Chongqing logistics Opening to the outside world and economic and social development have made great contributions. Zhou Jianting said that during the "14th five year plan" period, Chongqing Jiaotong University will actively integrate into the national strategic needs, focus on six key areas: intelligent transportation, ecological environmental protection, strengthening the foundation and improving the quality of traditional disciplines, intelligent manufacturing of transportation equipment, intelligent construction and transportation culture and art, and strive to achieve international leadership in the field of super large bridges in mountainous areas, Promote the expansion of scientific and technological achievements from quantity to more emphasis on the transformation of visual quality, strengthen the leading role of academician and expert team, and better promote the school to serve the national strategy and local economic and social development.
