Application of tabu search to calculating safety factor of slope stability
Yang Xiao-jun · Rock and Soil Mechanics · 2005
Slope stability calculations are usually done in the framework of limit equilibrium analysis. Safety factors are calculated for every slip surface; and the lowest value of safety factor characterizes the safety of the entire slope. During the calculating process of slope stability safety factors are treated as function of the coordinates of the potential slip surface center and radius of the potential slip surface. By applying tabu search for continuous variables the safety factors of slope stability are calculated. The safety factor calculated by tabu search is globally optimal. Thus the reliability of slope stability calculation is improved.
