<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>

<p>This paper deals with fully grouted rockbolts, both for mining and civil engineering applications. Their mechanical behavior under tensile loads is reviewed theoretically and experimentally. As for the theoretical part, a new solution able to predict the ...

The morphological and geological setting of Greece, the active tectonics and the irrational human activities results to the fact that several natural sightseeing areas or even more, archaeological sitesand monuments are located in areas with unfavourable geotechnical ...

An extensive axial test program has been used to quantify the difference between the static and dynamic capacities (kN/m of embedment) for friction rock stabilisers once sliding starts. Rough simulated boreholes have been developed for the installation and ...

This paper presents the preliminary results of a laboratory testing program aimed at assessing the impact energy dissipation capability of a new rock bolt. The results represent the most up to date findings at this current time. In situ field tests are still ...

This paper presents case studies for both rock mass modulus and rock mass shear strength in an attempt to assess the validity of the approach of using GSI and the Hoek-Brown criterion. It is concluded that for some rock masses the method works well, but in ...

The drive for mechanization of stoping operations on South African platinum, gold and chrome mines is favouring stope support by rock bolts rather than the traditional volumefilling support methods such as mine poles. Many of the stopes are less than two metres ...

A systematic program of testing of different reinforcement systems has been undertaken since 2004. Potentiometers, load cells, accelerometers and high speed video are used to monitor the tests. Software has been developed to analyse the data. The results from ...

<p>This paper describes the methods that can be used to optimize the design of tunnels using a combination of reinforcement and support methods. Particular attention is given to tunnels in very weak rock or soil in which large deformations can occur. Two case ...

The authors wish to explore the possibility and practicality of making use of new generation support products to make the operation safer as well as enhance productivity in the development phase and during the undercut operation. This paper will attempt to ...
