The Kemano hydroelectric facility was constructed in the s to supply power to the aluminum smelter in Kitimat, on the west coast of British Columbia. The Kemano project includes a 16 km long water conveyance tunnel that set world record advance rates in the s, and 8 km of a partially completed tunnel. A risk management strategy was developed in the late s in case of collapse of the first water conveyance tunnel, and by the excavation of a second tunnel parallel to the first had begun. Work halted in due to environmental litigation and change in political climate.
In the owner of the Kitimat smelter and the Kemano hydroelectric facility announced plans to continue work on the tunnel that was left unfinished. This thesis is a collaboration with Hatch Ltd. Three dimensional finite element elastic stress modelling was completed in order to determine the in-situ stress conditions as well as the boundary stresses around the tunnel.
The of the stress modelling were incorporated into a Bayesian Belief Network that was developed for the Kemano tunnels. It was built using widely accepted empirical relationships in rock mechanics, expert judgement and conditional relationships between inputs. This network predicts the ground class at a user-defined chainage, based on a database that was developed from project literature.
The user is also able to input new data as it becomes available, for example during the tunnel advance. The predicted ground class was plotted as a function of chainage, and may be used as a comparison to the support requirements that have been determined thus far.
