Deep excavations in urban environments present unique challenges due to space constraints, adjacent structures, underground utilities, and complex soil-structure interactions. The increasing demand for underground infrastructure—such as subways, basements, underground parking, and utility corridors—requires innovative design approaches and strict control during construction to ensure safety, performance, and minimal disruption to urban life.
This session will explore the geotechnical and structural aspects of deep excavations, with a focus on modern design practices, construction methodologies, monitoring techniques, and risk mitigation strategies. Emphasis will be placed on case studies and lessons learned from real-world projects in dense urban contexts.
The aim of this session is to bring together engineers, researchers, and practitioners to share knowledge, best practices, and technological advancements related to deep excavation projects in cities. Key topics will include, but are not limited to:
– Numerical and analytical modeling of deep excavations
– Soil-structure interaction and retaining system performance
– Ground improvement techniques for excavation support
– Instrumentation, monitoring, and performance evaluation
– Impacts on nearby structures and mitigation measures
– Groundwater control and dewatering challenges
– Construction sequencing and risk management
– Preparation and use of Geotechnical Baseline Reports (GBR)
– Regulatory and environmental considerations
The session invites both academic and industry contributions, especially those based on complex urban projects with innovative approaches to design and construction.
