Objective Based on previous geotechnical knowlegde, this course is introducing the different tunnel construction methods, the principles of tunnel design and the failures, maintenance and renovation of underground structures.
The topic focuses on the design process of underground structures. The students will be able to determine the main input data for tunnel design, will know the tunnel excavation method, and can choose an adequate tunneling method to solve a specific problem. We are also introducing the principles of waterproofing and tunnel maintenance.
After a successful exam the students will be able to actively participate in tunnel design and excavation processes and after some year of experience they will be able to manage tunnel design and tunnel excavation
