SYNOPSIS

The speaker will introduce the design approach of cavern in rock being adopted in Hong Kong. Cavern design in rock would begin with empirical design approach (such as NGI Q-system), followed by design check using the reinforced rock arch theory, and finally, verified using finite element method. The speaker will also present a case study from the Tseung Kwan O-Lam Tin Tunnel project where two caverns are situated closely to each other. Challenges and optimised  design of this particular project will also be discussed.
