Mitigation the Risk of Slope Failures: Hong Kong Experience

  • Albert Yeung, The University of Hong Kong, Hong Kong

The total area of the Hong Kong Special Administrative Region (HKSAR), China is only 1,103 km2, accommodating a population of 7 million as of mid-2009 and one of the world's largest financial and trading centers. However, most population is being housed in 215 km2 of urban development because of steep natural terrain and stringent planning controls. The high concentration of population and economic activities in such a small area exert an intense demand on land. Therefore, slopes are always formed to develop new land to cope with the rapid economic development of Hong Kong. As a result, these slopes are very close to human activities. After many fatal slope disasters have occurred early 1970s, the Government of Hong Kong has been implementing many initiatives to mitigate the risk of slope failures in Hong Kong. These implementations and measures will be discussed in the paper to share our experience with other ACECC economies.
