Triaxial Test for Embankment Dams: Interpretation and Validity

Source

For the construction of two large dams, several triaxial test series were executed on the embankment materials. The first material is an altered sandstone and the second a filter material. Several stress paths of loading were tested: extension test, constant mean pressure test, constant stress ratio, and conventional tests. The various causes of error in the experiments were examined: end restraint, bedding error, and membrane penetration. For a good estimation of deformation modulus, direct measurements inside the triaxial cell were developed. The general results are presented and the methods produced high quality tests. The effects of the grain size distribution were also studied: on the same material, triaxial tests with different specimen diameters were conducted for various maximum grain sizes.
