Taking the loess in Xi’an as example, the dynamic mechanics, basic mechanics and the flow characteristics have developed on research. The cyclic triaxial tests, unconfined compressive tests, ring tension tests, double punch tests, uniaxial punch tests, and uniaxial creep tests are conducted with remolded loess under different water content and different dry density. Based on the tests results, the resilient modulus, permanent deformation, critical dynamic stress, basic mechanical properties parameters (including compressive strength, tensile strength, and shearing strength), and the creep property of loess in Xi’an are conducted systematical research. This research work has the important theory and practice significance to each kind of Geotechnical engineering design in loess area. The main research achievements include: (1) Through the research on cyclic triaxial tests, the relational curves of resilient modulus with deviation stress of undisturbed loess and remolded loess can be obtained; constitutive its equation expressions. Through the permanent deformation tests, the permanent deformation curves and critical dynamic stress lever of remolded loess can be obtained. Compared the resilient modulus of undisturbed loess with those of remolded loess, and compared the change rule of these two kinds of resilient modulus with the water content. (2) Using different methods to determine the basic mechanical properties parameters of remolded loess, including compressive strength, tensile strength, and shearing strength. Contrast the determination results of each method, and analyze the serviceability of each method to determine the basic mechanical properties parameters of remolded loess. The change rules of basic mechanical properties parameters with dry weight density and water content are discussed. (3) Through the research on uniaxial creep tests, the creep curve and stress-strain tautochrone of remolded loess can be obtained. Use Burgers model to study it, and use Origin7.5 software’s misalignment fitting function to predict the creep equation and PRONY progression equation of the model, and analyze the influence of the model parameters.
