International Symposium on In-situ Rock Stress

International Symposium on In-situ Rock Stress

Trondheim, Norway, June 2006

Starting from June 18th to June 24th SINTEF together with Norwegian University of Science and Technology (NTNU) hosted an ISRM sponsored international symposium on in-situ rock stress. The symposium venue was the university campus. A symposium on this specific topic has now been arranged for the fourth time; Stockholm (1986), Kumamoto (1997), Kumamoto (2003) and now in Trondheim (2006).

The conference participants enjoyed a “get-together” in the Archbishops Palace on Sunday night, sponsored by the Trondheim Community, and hosted by the Mayor Ms. Rita Otervik who welcomed the participants to Trondheim and the conference. During the three following days the symposium addressed topics of special interest for professionals who are active in science and engineering concerning rock mechanics in such areas as: pre-investigations, stress measurements, numerical analysis, tunnel and cavern design, mining, oil and gas exploitation and relevant geological processes. 120 participants were registered to the symposium, which was very much in line with the expectations of the organisers.

Altogether approximately 70 scientific oral presentations were given during the three days following the opening speeches and invited key-note lectures. The presentations were organized into five different categories: - Stress measurement by hydraulic fracturing and overcoring - Stress estimates by other means - Engineering applications of in-situ stress - Interpretations of in-situ rock stress - Database, world stress map and miscellaneous

The proceedings that include full text of all articles presented in the symposium contain 500 pages and can be ordered by entering the symposium web site (ISBN 0415401631).

The symposium banquet was given at Ringve Museum. Ringve houses Norway's National museum of music and musical instruments with collections from the whole world. During the dinner a fiddler entertained the participants with some traditional Norwegian folk music.

A one day post-symposium course on RFPA was arranged. RFPA is a numerical testing tool for Realistic Failure Process Analysis of rock, concrete, composites and engineering structures. The course had 15 participants. A three day post symposium tour was offered to the participants. The tour went through some of the most spectacular regions of Norway, including high mountains and fjords, some major tourist attractions and a number of rock engineering sites including the world largest underground rock cavern for public use, Gjøvik Olympic Mountain Hall. 30 participants joined the post conference tour.
