Report Title : The Weathering Profile along the Coastal Area from Central To Kennedy Town, Hong Kong Island (2006), 18 p. plus 2 Figures

Author : Phoebe N.Y. Lau

Abstract

During the ground investigation stage for the International Finance Center I in Central District of Hong Kong Island, completely decomposed granite was revealed in a number of drillholes to a depth of -70 mPD. This demonstrated the presence of a zone of deep weathering. Similar deep weathering conditions have been noted further west along the coastal area between Shek Tong Tsui and Kennedy Town. This study was undertaken, therefore, to assess the subsurface geology of the coastal area in the northwest of Hong Kong Island, extending from Central to Kennedy Town, to in particular to confirm the nature and extent of deep weathering within the study area. The data used in this study are held within the Geological Modelling System (GMS) maintained by Planning Division, on behalf of Geotechnical Engineering Office, Civil Engineering Department.
