Underground Space Technology

The Underground Space Technology course provides a comprehensive understanding of the planning, design, construction, and management of underground spaces used for civil engineering infrastructure. With increasing urbanization and limited surface space, the course explains how underground space offers efficient and sustainable solutions for transportation systems, utilities, storage facilities, and public infrastructure.

The course integrates concepts from engineering geology, rock mechanics, and geotechnical engineering to address the challenges associated with underground construction. Learners study subsurface investigation techniques, in-situ stress conditions, rock mass behavior, and ground–structure interaction. The course also covers excavation methods, ground support and lining systems, construction sequencing, and safety measures required to ensure stability during and after construction. Emphasis is placed on risk assessment, monitoring, and control of ground movements, which are critical in urban tunneling and underground works.

By the end of the course, learners gain the ability to understand underground project planning, select appropriate construction and support methods, interpret field data, and contribute to safe and economical underground infrastructure development.
