A new harmony search method is presented in the location of non-circular slip surface of soil slopes. It differs from the basic harmony search method in the flowing two aspects. Firstly

a kind of two-point search strategy rather than random search strategy is adopted to take full advantage of the accumulated information in the harmony memory. Secondly

a correcting strategy is substituted for the penalty strategy to render the inadmissible slip surfaces to be acceptable. The stability analyses of two soil slopes are evaluated by the new harmony search method. Comparisons between the existed results and the results from the new harmony search method indicate that the proposed strategies are valid and rational.
