ACUUS 2027：A milestone event of historic significance.

Since its establishment in 1987, ACUUS has journeyed through 40 years, hosting 19 conferences globally and emerging as the most influential international platform in the field of underground space development.

It has been nearly 20 years since ACUUS was last held in mainland China. This not only recognizes China’s achievements in the field of underground space but also serves as a profound dialogue between global expertise and Eastern practices. ACUUS 2027 will bring together scholars, engineers, policymakers, and industry leaders from around the world to collectively explore the future development directions of underground space.
