Publ Rotterdam: A A Balkema, 1977 Describes a project to drive a road tunnel through Pleistocene deposits of stoney gravels containing silt amd sara. D~crmation stress measurements were made in a test tunnel, and a 3-dimensioral analysis carried out by the finite element method. A significant difference between measured and calculated stresses is noted. It is concluded that the soil is acting as an additiomal support system. 793113 DISPLACEMENT MEASUREMENTS AS A MEAN FOR SAFE AND ECONOMICAL TUNNEL DESIGN Carvalho, 0 S; Kovari, K Proc International Symposimn on Field Measurements in Rock Mechanics, Zurich, 4-6 April 1977, V2, F709-721.
