Learning Outcomes : Upon successful completion of the course, the student will be able to: • Understand the different types of tunnels and their design requirements, excavation methods, the complexity of tunnel projects, and the necessity of different disciplines participating in their implementation. • Understand the tunnel design process and the technical, economic, and social factors affecting it. • Identify and design the most technically suitable excavation method taking into account all constraints. • Understand the distinction of mechanized tunneling in different geotechnical conditions and determine the type of equipment to be used in each case. • Understand the requirements of the geotechnical investigation and geotechnical monitoring program for tunnel design and construction in soils and rocks.
