- W2000914825 abstract "To determine the safe distance between spreader and the upper verge of dump slope, a 2D and 3D slope model was built respectively, the limit equilibrium method and the finite element method with shear strength reduction technique (FEM-SSR) were introduced to analyze the stability of the spreader. For the slope under the action of variable external loads, the simple genetic algorithm (SGA) sometimes fails to converge to the global optimum, for this reason, an improved optimum maintaining simple genetic algorithm (OMSGA) was utilized to search for the critical slip surface, and the probability of the global convergence was improved greatly. On the basis of the three-dimensional elastic-plastic finite element model of the dump slope, the minimum sinkage of spreader track which interferes the spreaders normal operation was taken as the criterion to determine the safety factor, according to this idea, the deformation in the elastic stage during the process of strength reduction was considered, and a more reliable safety factor by the variable stiffness method was obtained." @default.
