ACUUS2027 – 第 20 届国际城市地下空间联合研究中心会议（ACUUS2027）

Nanjing, a city that blends the timeless grace of a six-dynasties ancient capital with the vibrant energy of a modern metropolis. Here lie the national intangible cultural heritage treasures such as Yunjin brocade and gold foil craftsmanship; here also stretch the modern urban arteries forged by an extensive metro network, underground commerce districts and smart utility tunnels. This city vividly interprets the unique “Chinese model” where tradition and modernity intertwine and thrive.

The International Associated Research Centers for the Urban Underground Space (ACUUS) is dedicated to fostering collaboration among experts in the fields of urban underground space research, planning, development, utilization, and management. Its core mission is to provide a platform for urban underground space, enabling global practitioners to reach consensus on initiatives related to underground space development and infrastructure utilization, ultimately benefiting urban life.

As a pioneering force in advancing the global underground space sector, ACUUS influences both academia and industry. Its membership encompasses over 20 renowned institutions worldwide, including the French Association of Tunnels and Underground Spaces (AFTES), Beijing Jiaotong University(China), China Research Center for Tunnel and Underground Space Engineering, Colorado School of Mines(USA), U.S. Center for Underground Construction and Tunnel Engineering, and the Swiss Federal Institute of Technology in Lausanne (EPFL). With a history spanning 40 years, ACUUS has held 19 biennial conferences in cities around the world and has evolved into one of the most prominent academic conferences in the field of urban underground space globally. The 20th World Conference of the Associated Research Centres for the Urban Underground Space (ACUUS 2027) will be held from November 6–11, 2027, in Nanjing, China.
