  • Tridimenzionalni porušni mehanizmi za določitev pasivnega zemeljskega pritiska
    Vrecl-Kojc, Helena
    The paper presents the modified three-dimensional failure mechanism for the determination of 3D passive earth pressure coefficient within the framework of limit analysis theory. The numerical results ... of limit values of 3D passive earth pressure are presented by non-dimensional coefficients of passive earth pressure influenced by the soil weight ▫$K_py$▫ and a coefficient of passive earth pressure influenced by surcharge ▫$K_pq$▫. This research was intended to improve the lowet values obtained until now with the limit analysis theory. In the paper there is also a brief description of the world recognized failure mechanisms, first translational and second a rotational hyperbolic failure mechanism that just so has been based on the limit analysis approach. The results are presented in a graphical form depending on geometrical parameters and soil properties. At the end, the comparison of results is presented.
