The Numerical Simulation on the Dynamical Character of the Stabilized-Soil

This article uses finite element ABAQUS to set up the 3-dimensional finite element model of the dynamic tri-axial specimen, simulate the dynamical deformation behavior of the stabilized-soil under cyclic load. The main focuses on the freezing temperature of the strengthen soil of the plastic deformation. Meanwhile, the influence to the strengthen soil dynamical characteristic such as cyclic load´s magnitude, the number of cyclic load, frequency, confining pressure and damping factor was researched by the method of numerical simulation. Within the accuracy and reliability of the allowable range, using the finite element simulation method to replace the dynamic tri-axial test, it Will greatly save the test of time, manpower and money, meanwhile it will expand the scope and sophistication of research parameters, it will provide an effective means for the study of the soil constitutive relationship models and more complex influencing factors.
