A plane strain apparatus for soils Vaid, Yoginder Pal


An apparatus has been designed to investigate the mechanical behaviour of soils under plane strain. Provision has also been made to consolidate specimens under condition of no lateral yield prior to their shear; thus simulating the consolidation state in natural sedimentary deposits. The apparatus is suited for testing both sands and clays, including undisturbed clay samples from standard size bore hole samplers. The design permits a variety of stress paths to be followed during shear. An experimental procedure for testing both sands and clays has been developed and some test results are described. The results obtained show a general confirmation of existing information on the behaviour of soils under plane strain.
