About the Course
Expanding cities necessities vertical expansions above and below the ground. Effective usage of underground spaces for transportation and storage facilities is the key to achieve these expansions. A comprehensive understanding of the execution of deep excavations for construction of these underground facilities is vital for an Engineer in this infrastructure era. This course has a systematic and concise treatment to geological and geotechnical aspects of deep excavations and tunneling, Construction methodologies for tunnels, caverns and shafts, Instrumentation monitoring of underground construction, Support systems for deep excavations, Software tools like PLAXIS 2D, WALLAP, RocLab and code provisions in deep excavations and tunnels.
Course Objective
- To introduce various underground structures such as tunnels, caverns, shafts and UG stations.
- To explain the construction methodology, support systems like diaphragm walls, sheet piles and challenges in the constructions of tunnels, caverns, shafts, and stations
- To cover design aspects in the field on geotechnical/rock engineering and tunneling, Instrumentation and monitoring of tunnels.
- To introduce geotechnical software tools.
Key Topics
Learning Outcomes
- Comprehend the different soil investigation techniques, rock mass classifications, components of different underground structures and their functions
- Design and apply different construction methodologies for tunnels, Caverns and shafts in different soil and rock conditions
- Create an instrumentation monitoring plan for tunnel construction.
- Evaluate the suitability of different excavation supports such as sheet piles, soldier piles, diaphragm walls and tunnel support for different soil and rock conditions
- Comprehend the use of different software tools like PLAXIS 2D, WALLAP, RocLab in deep excavations and apply code provisions for mitigating water ingress and seepage in excavations and tunnels.
