What lies beneath; a decade of underground construction in Hong Kong
Quarterly Journal of Engineering Geology and Hydrogeology (March 2018) 51 (3): 301-310


Over the past decade Hong Kong has seen a rapid expansion in the use of underground space for Civil Engineering infrastructure projects (Fig. 1). Forty-eight kilometres of rail tunnel has been or is in the process of being constructed with associated shafts (Fig. 2) for access and ventilation and mined caverns for stations (Fig. 3). The catalyst for this expansion may be due to the integration of the Hong Kong Special Administrative Region with China, which commenced in 1997 (with the handing back of Hong Kong and the New Territories to China) and has accelerated over the last decade in line with the global aspirations of China. This integration has been the catalyst for three new major road border-crossing projects (Deep Bay Link; Hong Kong to Macau Bridge; and Liantang/Heung Yuen Wai crossing) and connection into the mainland express rail link (Hong Kong High Speed Rail Project) (Fig. 1). The population has also risen over this period from c. 6.9 million in 2005 to c. 7.3 million in 2016 (tradingeconomics 2016) fueling, in part, the expansion of mass transit rail systems: the Kowloon Southern Link (3 km - complete); the West Island Line (3 km - complete); Sha Tin to Central Link (17 km - under construction); the South Island Line East (7 km - under construction); the Kwun Tong Line extension (3 km - under construction) and the Hong Kong Express Rail Link (26 km - under construction) (Fig. 1). Pressure on valuable land resources has seen the emergence of the innovative use of underground space for: explosives magazines; sewage treatment systems; service reservoirs (Fig. 4); urban drainage and flood protection projects (Fig. 5); and new road networks, such as the Central-Wan Chai Bypass (Fig. 6).
