6月14日,中國科協副主席、中國工程院院士何華武在召開的2019世界交通運輸大會上表示,輪軌高鐵運行速度的進一步提升,受到輪軌關系、弓網關系、流固耦合關系、運行環境等因素的制約,未來高鐵技術若要實現速度上的突破,可將高速磁懸浮或低真空管(隧)道高速磁懸浮鐵路作為研究方向。
何華武透露,中國工程院牽頭組織相關方,正在開展《管(隧)道磁懸浮交通發展戰略研究》《大灣區廣深港高速磁懸浮鐵路預可研》等重大課題研究,擬對不同制式高速磁懸浮,結合低真空管(隧)道技術路線及關鍵技術問題進行充分論證,研判技術經濟可行性,并對粵港澳大灣區廣深港通道建設高速磁浮鐵路先行路段,開展工程預可行性研究。
其實,早在1904年,美國學者羅伯特·戴維就曾提出“真空管道運輸”的設想。近年來,埃隆·馬斯克對“真空運輸”這一概念進行了豐富,提出了“超級高鐵”的理念。其原理是,通過磁懸浮技術和真空環境的結合,實現幾乎零阻力的運輸效果,真空管道內的膠囊狀座艙就像是一顆炮彈一樣被彈射出來,理論上時速可以達到1500公里,而座艙里的乘客卻只能感受到很小的爆發力。目前,中國國內有西南交通大學、中國工程院、北京交通大學、中國航天科工集團等多家機構和企業正在對該項技術進行研究。
最新消息顯示,正在研制的中國超級磁懸浮列車“超級高鐵”,采用“高溫超導磁懸浮+真空管道”技術,未來的時速可達到每小時1000公里,預計最快2年后可能會投入試行。

On June 14, He Huawu, vice chairman of the Chinese Association of Science and Technology and a member of the Chinese Academy of Engineering, said at the 2019 World Transportation Congress that the further improvement of the speed of the high-speed rail was constrained by factors such as wheel-rail relations, bow-network relations, fluid-solid coupling relationships and operating environment, and that the future of high-speed rail technology should achieve a breakthrough in speed.
High-speed magnetic levitation or low vacuum tube (tunnel) high-speed magnetic levitation railway can be used as the research direction. He Huawu revealed that the Chinese Academy of Engineering led the organization of relevant parties, is carrying out "tube (tunnel) road magnetic levitation traffic development strategy research" "Great Bay Area, Guangzhou-Shenzhen-Hong Kong high-speed magnetic levitation railway pre-research" and other major topics of research, to different high-speed magnetic levitation, combined with low-vacuum pipe (tunnel) road technical routes and key technical issues to fully demonstrate,
To determine the technical and economic feasibility of the project and to carry out a pre-feasibility study on the construction of a high-speed maglev railway in the Guangzhou-Shenzhen-Hong Kong-Shenzhen-Hong Kong Corridor, Guangdong, Hong Kong, Guangdong and Hong Kong. In fact, as early as 1904, the American scholar Robert David put forward the idea of "vacuum pipeline transportation". In recent years, Elon Musk has enriched the concept of "vacuum transportation" and proposed the concept of "super-high-speed rail". The principle is that through the combination of magnetic levitation technology and vacuum environment, to achieve almost zero resistance transport effect, the capsule-shaped cockpit in the vacuum pipe is ejected like a shell, theoretically can reach 1500 kilometers per hour, while passengers in the cockpit can only feel a small burst force. At present, China has Southwest Jiaotong University, China Academy of Engineering, Beijing Jiaotong University, China Aerospace Science and Technology Group and other institutions and enterprises are studying the technology.
The latest news shows that the chinese super maglev train is being developed, "super high-speed rail", using "high temperature superconducting magnetic levitation and vacuum pipeline" technology, the future speed can reach 1000 kilometers per hour, is expected to be as soon as 2 years later into trial.
