Laboratory Positioning：

Aiming at the double bottleneck problems of shortage of land resources and deterioration of urban environment in the process of urban construction and development in Beijing and the whole country, with the goal of developing and using urban underground space, the focus is on the exploration of urban underground space geological conditions detection, engineering planning, design and construction, use environment and safety Basic theories and key technologies in the field of security and other fields, build a public platform for basic research, technology research and development, and talent training in the field of urban underground space engineering, assist the construction of the urban sponge function in Beijing, and provide technical guarantee for the realization of sustainable urban development.

Key Scientific Problems and Key Technologies to be Solved:

(1) Urban underground space geological conditions and constructability analysis theory and evaluation method

(2) The function of urban underground space and its correlation with the function of urban sponge

(3) Disturbance effect of underground engineering excavation and stratum precise control technology under complex urban conditions

(4) Interaction mechanism of underground space and urban environment and habitability guarantee technology

Research Direction:

(1) Fine exploration of urban engineering geology and appraisal of suitability of underground space Aiming at the planning, design, development and utilization of urban underground space projects, it focuses on the investigation techniques and equipment, experimental analysis techniques and methods adapted to the urban working environment and engineering characteristics, Appraisal methods and standards for constructability, temporal and spatial variability and evolution of urban underground engineering geologic characteristics. Connect and interact with existing underground infrastructure. Underground space development planning and urban construction and development, coordination and coordination with the city's mid- and long-term planning, and formulation of relevant policies and measures for urban underground space development.

(2) The new theory of urban underground space engineering planning and design is aimed at the special resource of urban underground space, focusing on the study of the relationship between its development and use, geographical economy, transfer transactions, property rights period and other multiple attributes and its definition methods and standards; underground space Development planning and urban construction and development, coordination and coordination mechanism with urban mid- and long-term planning, basic performance and variability of formation rock and soil under complex underground geological conditions in cities, design of different underground space projects and their structures and structures Theories and calculation methods, experimental analysis techniques and methods, and environmental effects analysis of underground space engineering under multiple constraints.

(3) Construction technology and risk management of urban underground space engineering Aiming at the particularity of urban underground engineering construction environment and operating conditions, it focuses on the research of new technologies, new processes and new equipment for underground engineering construction suitable for urban environments; different construction methods on urban ground The influence of building and surrounding environment and its control technology, etc.

(4) Urban underground space environment and durability of underground structure Urban underground environment and durability of underground structure. Aiming at the complex and changeable characteristics of the urban underground environment, focus on the study of the time and space distribution of the geological environment, water environment, corrosive media, and harmful media in the urban underground environment and the mechanism of its impact on the safety of underground engineering, building structures, and service facilities , Control technology, durability design, reliability evaluation, etc.

(5) Safety assurance and intelligent monitoring of urban underground space engineering In view of the particularity of urban underground space engineering, it focuses on the application of digitalization of the entire life cycle of urban underground space in planning, design, construction and operation and maintenance management. Using modern Internet of Things sensing technology combined with the Internet to study the comprehensive intelligent monitoring technology of underground space projects, providing services for disaster prevention and control such as flood control, fire protection, earthquake resistance, terrorist attacks, and public safety services such as emergency hedging and emergency rescue.

The urban underground space engineering laboratory research base mainly relies on the School of Civil and Environmental Engineering of Science and Technology of Beijing（USTB）. The laboratory has a construction area of 2300m2. Around five main research directions, eight major experimental platforms and systems have been constructed.

There are 57 researchers in this laboratory, including 22 professors and 18 associate professors.Among all researchers, there are 1 academician of the Chinese Academy of Engineering, 1 chairman of the International Academic Institutions Committee, 1 member and convener of the Disciplinary Review Group of the State Council, 1 National Teaching Teacher, 1 National Outstanding Youth,3 people selected into the national “One Million Talents in the New Century” and three people selected into the “New Century Excellent Talents Support Plan” of the Ministry of Education
