Course Objectives
The course is designed to introduce to students the basic principles of geotechnical design and construction of railway and metro tunnels. Some technical issues relating to type and method of construction and design of tunnels in different ground conditions are presented. Helpful tools to assess the loads on tunnels and tunnel construction techniques fitting the local geological conditions are given. The main emphasis is to show the students the excitement associated with tunneling and the fact that many unknowns exist which require many years of experience and engineering judgment.
Course Content
Development of railway and metro tunnels. Profiles and cross-sections of railways and metros. Theories of vertical, lateral and bottom pressures. A numerical example by segment design. Novel techniques and equipment used in construction. Metro tunnel characteristics and general pattern of planning. Subway and deep level stations. Ventilation and aerodynamic aspects. Some important examples. NATM method and cost calculations.
Course Learning Outcomes
The students will be able to;
- Define reasons for tunneling and its historical development
- Classify tunnels and describe their geometrical design considerations
- Estimate the shear strength of intact rock, rock mass and joints
- Classify the rock mass according to various classification systems
- Compute the stress and load on tunnels by empirical and analytical methods
- Define the tunnel construction techniques in different ground conditions
- Describe the main principles of observational methods and NATM
- Construct ground response and support reaction curve using convergence – confinement approach and describe the interaction between ground and support
