The Immersed Tube Tunnel Branch of China Highway Construction Association Technical Exchange Conference & 2026 9th International Conference on Traffic Transportation and Civil Architecture (ICTTCA 2026) will be grandly held in Dalian, China, from April 10 to 12, 2026. With the continuous advancement of transportation infrastructure construction in China, immersed tunnels, as a crucial engineering technology for traversing complex marine and geological environments, are playing an increasingly key role in promoting regional connectivity, enhancing transportation efficiency, and supporting sustainable economic and social development.

The establishment of the Immersed Tube Tunnel Branch of China Highway Construction Association marks a new stage of more standardized, efficient, and innovative development in China's immersed tunnel field. Adhering to the core mission of "research, consultation, service, and communication," the branch fully embodies the principle of "serving the country, society, the public, and the industry," bringing together top experts, scholars, and scientific researchers in the immersed tunnel domain to build a high-end think tank and lead technological innovation and industrial upgrading. Through providing policy consultation, conducting major research projects, and formulating group standards, the Immersed Tunnel Branch actively promotes the transformation of scientific and technological achievements and science popularization, strengthens academic exchange and cooperation at home and abroad, and fosters continuous progress and application of immersed tunnel technology, injecting strong momentum into the high-quality development of China's immersed tunnel construction.

This conference will focus on the core technologies and cutting-edge developments of immersed tunnels, aiming to establish a platform for deep integration of government, industry, academia, research, and application. It seeks to promote the close combination of theoretical research and engineering practice, advance China's immersed tunnel technology to the global frontier, and jointly drive innovation and progress in the fields of global transportation and civil architecture. We sincerely invite you to attend this conference.
