Tunneling and Underground Construction Training Course

Introduction:

Tunneling and underground construction are critical components of modern infrastructure projects, providing essential solutions for transportation, utilities, and environmental management. This 5-day course introduces participants to the core principles of tunneling and underground construction, from design and excavation methods to safety measures, environmental considerations, and the technologies that enhance the efficiency and safety of underground projects. Through a combination of theoretical knowledge and practical application, participants will develop the skills needed to understand the challenges and opportunities of working below ground in urban environments.

Objectives:

By the end of this course, participants will:

  1. Understand the basic principles and challenges of tunneling and underground construction.
  2. Learn about different tunneling methods and techniques, including mechanical and manual excavation.
  3. Explore the role of geotechnical engineering in underground construction, including soil and rock behavior.
  4. Understand tunnel design, construction materials, and lining systems.
  5. Gain knowledge of safety practices, risk management, and environmental considerations.
  6. Learn about modern tunneling technologies, including Tunnel Boring Machines (TBMs) and ground support systems.
  7. Explore case studies of major tunneling projects and their successful outcomes.
