The stresses occurred in the middle slab at the areas of the emergency passageway in a double-deck tunnel are analyzed when the slab is lifted to replace bearing pads placed between the middle slab and supporting bracket as a maintenance process. The middle slab can be lifted at several different points near the emergency passageway areas and the stresses of the middle slab depend on the lifting points. This study presents the effect of the lifting location of the middle slab on the stress occurrence for the maintenance work of replacing bearing pads under the middle slab near the emergency passageway areas.
