TUNNELING ENGINEERING

 L T P C

3003

COURSE OBJECTIVES:
• Students mainly focused in visualizing and critically analyzing the behavior of underground structures with reference to various supporting systems under different loading conditions due to induced earth pressure on the underground structures.
• To give idea about the equipment used in underground excavations.

UNIT I

TUNNELS AND UNDERGROUND SPACE APPLICATION

9

History-caves-tunnels for transport-water,power supply-storage of LPG –nuclear waste disposal- defence facilities-submerged tunnels-underground library,museums.

UNIT II

EXCAVATION TECHNIQUES

Types and purpose of tunnels-choice of excavation methods-soft ground tunneling-hardrock tunneling-tunnel drilling-blasting-impact hammers-problems encountered and remedial measures.

UNIT III

PLANNING AND GEOMETRIC DESIGN OF TUNNELS

9

Topographical –geological survey-rock sampling-testing-determination of location size shape and alignment-subsidence problem on soft ground –tunneling design in hard rock.

UNIT IV

CONSTRUCTION OF TUNNEL

Advanced drilling techniques –TBM-cuttability assessment-shield tunneling-advantages-types of shield tunneling-factors affecting selection of shield-twin tunnel-NATM.

UNIT V

DESIGN OF TUNNEL SUPPORTING SYSTEMS AND VENTILATION

9

Classification of supports-active –passive-permanent-temporary-excavation support-steel supports- lining-grouting-ground freezing-environment in underground-various methods of ventilation.

TOTAL: 45 PERIODS
