Fast Triaxial Shear Device Evaluation

摘要

The purpose of this report is to define the nature of the problem posed in interpreting the results of testing soils with Fast Triaxial Device (FTRXD), to present the steps taken to date in the evaluation of the device, and to outline those planned for the future. The rapid loading of soils in a triaxial testing device was done by WES earlier in the 1960's in conjunction with research on the dynamic bearing capacity if soils. A dynamic triaxial test apparatus was designed and constructed. The results from testing with the apparatus on highly plastic clay specimens, 1.4 inches in diameter by 3.0-inches long, were used to interpret dynamic bearing tests of small plates resting on the clay. The apparatus, the results obtained from it, and their uses are described in Reference 1.
