<p>This Geoguide presents a recommended standard of good practice for rock cavern application and design in Hong Kong. The contents of this guide are derived from Scandinavian practice with suitable modifications for application in Hong Kong.</p>

Details are given of the analytical methods used to design rockbolts and shotcrete support for tunnels and large span caverns under relatively low cover in the near horizontally bedded Triassic sandstones of the Sydney region.

The paper presents the method for design of primary roof support for the large todoidal cavern constructed with 7m of rock cover beneath Sydney's Royal Botanic Gardens. Design of rock reinforcement using a combination of fully grouted rock dowels.

<p>Tunnel construction is one of the most interesting yet most diffi cult disciplines of civil engineering. It combines theory and practice to form an engineering art of its own, requiring wide-ranging knowledge and long years of experience in the fields of ...
