METHODS AND SYSTEMS OF USING AND OPERATING PERMANENT DEFORMATION MODEL FOR SOILS AND GRANULAR MATERIALS WITH THE SHIFT FACTOR CONCEPT

Abstract: the present disclosure describes embodiments of a permanent deformation model for soils and granular materials with the application of the shift factor (sf) concept. the model was structured following the guidelines provided by the standard dnit 179, but with the modification of the number of loading cycles and the stress pairs to be applied. instead of 150,000, 10,000 load cycles were used for each stress pair, with the exception of the most severe pair, for which 150,000 load cycles continued to be applied. from the results obtained for each stress pair, there is constructed a master curve representative of one of the test stress pairs, selected as a reference. embodiments of the present disclosure finds its field of application in the characterization of the permanent deformation of soils and granular materials.
