    Geomechanics Colloquium

    Here you get directly to the Geomechanics Colloquium.


    The Austrian Society for Geomechanics (OeGG)

    A group of Austrian experts started in the fifties of the 20th century to deal with rock engineering. This group was also called Salzburg Circle. As early as 1951 Leopold Müller organized a Colloquium about rock engineering and technological questions in Salzburg.

    In 1962 the International Society for Rock Mechanics (ISRM) was founded in Salzburg. Leopold Müller was the first president of the ISRM. The Austrian Society for Geomechanics (OeGG) was founded in 1968 as national group of the ISRM.

    The aims of the OeGG are to promote scientific research in all fields of geological and geotechnical engineering with all those involved in geotechnical research, construction, administration, improve geotechnical design and construction methods, and to publish scientific papers and guidelines.

    The society is divided into individual technical sections, each dealing with questions  related to geology, foundation and rock engineering, soil and rock mechanics, as well as tunnelling.

    Presently, the OeGG has approximately 585 regular members and 36 supporting members.

    The Austrian Society for Geomechanics is organizer and co-organizer of Colloquiums, Conferences, Seminars and Workshops.

    The OeGG's hallmark event is the annual Geomechanics Colloquium in Salzburg.

    This colloquium is one of the world's largest annual conference on geotechnics, consistently with more than 800 participants. It developed to a meeting place of researchers, designers, contractors, owners and manufacturers.

    The interdisciplinary nature of the Colloquium represents the vision of the OeGG. In addition to technical issues, contractual and economical aspects are discussed.

    Seminars and workshops on special technical topics are organized the day before the Colloquium, which have seen increasing attendance over the past several years.

    Every second year, the OeGG co-organizes the Austrian Tunnel Day. In addition, the OeGG supports events organized by the Graz University of Technology, Vienna University of Technology and Leoben University of Mining. All these events are designed to fulfill the objective of the society to support the exchange of knowledge.
