| Objective : | 1. Construction pits The student shall gain knowledge about and understanding for the special problems and characteristics of design of Construction Pits with special emphasis on pits with bottom below groundwater table. The student shall be able to plan the construction and design the structures in a Construction Pit. 2. Tunnel Construction The student shall gain knowledge about and understanding for the different types of tunnel structures. The student shall be able to plan the construction and design the structures for tunnel and approaching structures. The student, who has met the course objectives, are at the final exam able to: • Analyse and assess different types of tunnel structures considering the function and the physical environnement. • Analyse, assess and design tunnel structures. Explain the choice. • assess the need for and range of dewatering. • Explain the chosen dewatering method and design a dewatering system. • Make slope stability analysis. • Present and explain the team cooperation. |
