    Abstract

    The paper presents the 1986 practice at the Norwegian Geotechnical Institute (NGI) for triaxial testing of soils that are fully saturated in situ. The test procedures for specimen mounting, saturation, consolidation, and static and cyclic shearing are outlined. Sample disturbance, specimen height, end friction, and anisotropic consolidation are discussed at length. Simplified procedures for anisotropic consolidation according to soil types are proposed. Sources of error are mentioned. A new method to measure the initial shear modulus in triaxial soil specimens is described.

    Keywords:
