General Overview
The Design and Construction of Tunnels and Underground Passages course is an advanced theoretical training program aimed at providing a comprehensive understanding of the engineering and technical principles underlying the design and implementation of tunnels and underground corridors in urban and mountainous environments. This course focuses on theoretical concepts that enhance the ability to analyze geological conditions, select appropriate construction methodologies, and design supporting structures, with a primary focus on safety, efficiency, and sustainability.
The content is delivered entirely theoretically, without relying on practical exercises or simulation software. This makes it ideal for civil engineers, construction engineers, and project supervisors who need to build a strategic understanding before moving to field execution. The course addresses concepts of geological investigations, excavation techniques (such as TBM, Drill & Blast, and Cut & Cover), the design of linings and supporting structures, groundwater management, as well as the importance of safety, continuous monitoring, and the project’s environmental impact. It also highlights the technical and regulatory challenges in major projects and the role of digital transformation, such as BIM, in improving design and implementation.
General Objective
The Design and Construction of Tunnels and Underground Passages program aims to enable participants to gain an in-depth theoretical understanding of the engineering framework governing tunnel projects. It focuses on the application of international best practices in design and construction. The program seeks to build trainees’ capacity to analyze geological conditions, understand how to choose the appropriate excavation technology, and make decisions that reduce risks and improve efficiency. Furthermore, it focuses on enhancing awareness of the importance of proactive planning, continuous monitoring, and the role of engineering in supporting sustainable infrastructure. This program does not require field execution experience; instead, it presents concepts in an analytical and organized manner to build a comprehensive vision of modern tunnel engineering.
