Investigation of Plane Strain Shear Testing. Report 1. WES High-Capacity Plane Strain Shear Apparatus

摘要

The objectives of the investigation was to build an apparatus that will enable soil testing under plane strain conditions and to demonstrate the performance of the new plane strain apparatus in testing crushed Napa basalt. The first objective was met by building a new plane strain apparatus to test cohesionless soils under plane strain condition at a wide range of densities and confining pressures. The second objective was satisfied by conducting four different plane strain tests on crushed basalt prepared at 70 and 100 percent initial relative densities.
