URBAN INTEGRATED UNDERGROUND SPACES
In this keynote, Han Admiraal will look into the contemporary use of urban underground space and argue that we need to leave the age of single use spaces behind us. As we enter the Anthropocene, the era representing humankind’s interference with the natural processes, we need to find new ways of using underground spaces. This requires these spaces to be used for multiple uses, contribute to preventing overshooting the ecological ceiling, contributing to the social foundation of cities, and be part of circularity. It will be argued that if underground space use has a role to play in the future of our cities, that role must be one of helping cities meet the challenges they face. The keynote will draw on examples and principles given in the book ‘Underground Spaces Unveiled: Planning and Creating the Cities of the Future’, which Han Admiraal co-authored together with Antonia Cornaro.

Smart Technology for Settlement Control Towards Zero Deformation Shield Tunneling
Settlement control has always been the first concern for all the participants of shield tunneling construction when the shield TBM passes through sensitive buildings, especially in urban areas. This keynote presents the practice of smart settlement control technologies in shield tunneling construction, including the ground penetrating radar (GPR) based tail void grouting detection, deep learning based tunnel face pressure prediction, and real-time sensing the tunneling parameters as well as the settlement. Morever, the applications of shield TBM passed through raily trakcs, adjacent buildings, power tunnels and operation subway tunnel are demonstrated, which achieved nearly zero settlement control.

More smart underground space and infrastructure to mitigate and adapt to climate change
As global temperatures increase with climate change, developing countries develop and urban populations increase so the demand for air conditioning increases. The air conditioning, although improving in efficiency with time, will require more electricity which in turn needs more infrastructure and without care could mean more fossil fuel consumption. This is important as already buildings contribute over a third of the world’s greenhouse gas emissions. One possible solution is to have more underground buildings or use more earth sheltered buildings to reduce the need for air conditioning. This paper explores the background, the latest developments to thermal comfort and air conditioning and the driving forces of climate change and the urban heat island. It then examines the hypothesis for more underground buildings and whether it could reduce the need for air conditioning.

Tunneling-induced effects on neighboring structures: how to manage the risks within design and construction?
The conference will deal with the effects of tunnelling (mainly from ground movements) on the neighbouring constructions (i.e., buildings, structures and utilities potentially being affected by the works). It will bring some responses to questions arising in present practice due to the strong relaunching of underground works in urban areas : how to manage the project within a risk-based approach ? how to gather data on the neighbouring structures so as to allow a reliable vulnerability assessment ? what knowledge has been recently gained from experimental and theoretical results on the mechanical interactions between the tunnelling works, the ground and the surrounding structures ? how to to spread them into operational practice ? what innovative constructive solutions and measuring devices ? The conference will be illustrated through recent case studies from TBM as well as conventional tunnel excavations.

Progresses on intelligent construction and operation maintenance of urban under-lake tunnels
China is currently at an important stage of urbanization. In recent years, the number and scale of under-lake tunnels in southern cities of China are growing consistently, which brings opportunities and challenges in intelligent construction and operation maintenance. Due to the long length of the under-lake tunnel, the large volume of concrete to be cast, the complex environment of the buried section and the underground environment of the lake bottom, the hydration heat and stress crack have been the main challenges of the under-lake tunnel engineering in crack control and waterproofing aspect. Simultaneously, with the development of big data, intelligent construction, information technology, and other techniques, these techniques are gradually applied to the whole life cycle of tunnel engineering including survey, design, construction, operation, and maintenance. The construction of the lake tunnel project is setting off a new round of technological innovation. This paper systematically summarizes the technical breakthroughs and application of technologies such as intelligent construction and information technology in the construction of under-lake tunnels in China, and puts forward reasonable suggestions on the key technologies of intelligent construction and operation maintenance for urban under-lake tunnel engineering.

Pros and cons of smart valorisation and re-use of abandoned underground cavities
This Keynote lecture deals with the sustainable development of abandoned cavities and underground structures. We discuss the pros and cons of such actions. In fact, France has had a significant historical underground activity. These cavities must be intelligently managed and valued. Cavities should not only be considered as a source of nuisance or risk but may also be an element of sustainable development. The challenges of the society including climate change, energy and ecological issues, calls for a change in the organization and physiology of the city in order to move towards a more sustainable city model. The underground space can contribute to make the city sustainable.
The keynote presents some strategic orientations of valorisation of abandoned underground excavations: visits, storage, etc. We present the conditions and the urbanistic modalities of smart re-use of the underground “Brasserie” limestone exploitation(Paris – France) and discuss how these valorisations may contribute to the maintenance of voids and risk prevention.

Use of the smart city concept for underground space resiliency
The keynote presents first challenges related to the underground space hazards, which are related to natural disasters as well as construction, industrial and human hazards. It shows how resiliency could help to improve our capacity to cope with these challenges and then how the use of the smart city solution through smart monitoring, advanced data analysis using artificial intelligence and control system could enhance the underground space resiliency.
