Hong Kong’s new South Island Line and Shatin to Central Link requires the expansion of Admiralty Station into Hong Kong’s first 4 line interchange station. Already the busiest interchange station in Hong Kong, expanding this station without interrupting services involves major rock mechanics challenges.
The new platforms are housed in shallow cavern and platform tunnels immediately adjacent to the existing platforms and under high rise buildings. To facilitate connection with the existing station, the Island Line platform tunnel needed to be underpinned and up to 30m of rock below it removed, while keeping trains running safely above.
