| Abstract | The direct simple shear device was developed over a period of 5 or 6 years at the Norwegian Geotechnical Institute. The model used in these tests is described fully in a paper by Bjerrum and Landva in Geotechnique, March 1966. Its construction was inspired by a large field shear box, the results from which agreed much more closely with field performance than the values obtained from triaxial tests. The apparatus works extremely well on soft Norwegian quick clays but a problem of sliding at bearing surfaces arose in an attempt to use it on a sample of stiff Leda clay from Hiawatha Park near Ottawa. |
