About

A. About the RockMass.net site

Constructions in rock, such as tunnels, caverns and shafts generally involve so large volumes that the properties of the rock mass cannot be measured in the laboratory, and seldom in the field. Therefore, the rock mass properties have to be determined mainly from observations in the field.

This web page gives you information on how field observations can be performed and used in practical rock engineering.  The Rock Mass index (RMi) system has been developed as a tool in this field. Some parts of the RMi system are also described in the Handbook on Engineering geology and rock mechanics, issued by the Norwegian Rock Group affiliated ISRM and IAEG. Also the textbook Rock Engineering contains useful information on classification systems, including the RMi system.

The rockmass.net website has also information on other items related to engineering geology, rock engineering and design, as well as to rock mechanics for information and help to those involved in applied geology in rock constructions.

 

B. Information on the RockMass company

The RockMass consulting company works in the fields of engineering geology and rock engineering with vast Scandinavian and international experience.

 

C. Information on the author of the rockmass.net site

Dr. Arild Palmström, the author of this web site, has a M.Sc. from the Norwegian Technical University of Norway in 1967 and Ph.D. from the Oslo University, Norway in1995. He has more than 40 years of experience in applied geology, rock engineering and design.

Information

 A. ABOUT THE SITE

The rockmass.net web site has existed since year 2000. Two earlier versions have been presented: version 1 in 2000 to 2008 and version 2 in 2008 – 2011.

Version 3 was launched in March 2011.

Unfortunately, the version 2 of the site was destroyed by a hacker in January 2011. (Who could have any interest of doing this of a site on information only?)  

Sorry for the down-time period in February and partly March 2011.

It is hoped that the new layout and content of the rockmass.net page can be of interest and a help to people practicing in planning, rock design and rock engineering.

This first presentation of version 3 of the site contains only the first issues of the new site. As you will find, lots of information remains, which from time to time will be made available when time permits.

 

B. INFORMATION ON THE  HANDBOOK IN ENGINEERING GEOLOGY

The book of 250 pages was launched in 2000.

 

C. INFORMATION ON THE  TEXTBOOK ON ROCK ENGINEERING

This book of 408 pages was launched in 2010. The layout of the book and at the same time the process in rock engineering is illustrated  here.
