Felsbau, October 2004 Edition on Bimrocks
The October 2004 edition of Felsbau Journal of Rock and Soil Engineering, edited by Dr. Edmund Medley. The Journal is sponsored by the Austrian Society for Geomechanics (http://www.oegg.at). The October 2004 edition was devoted to papers on bimrocks and included contributions on characterization, tortuosity, slopes, tunneling, and dams. Individual papers are as listed above. Also: the complete October 2004 edition of Felsbau is available (9MB).
The October 2004 edition is provided here with permission from the Chief Editor of Felsbau and the Publisher, VGE (Verlag GE, Essen) of Essen, Germany, who also provided the PDFs.
The October 2004 edition of Felsbau was dedicated to the late Professor Gunter Riedmueller (1940-2003), an outstanding international engineering geologist and a premier authority on the characterization of fault rocks, tectonic melanges and other bimrocks.
