GAs for soil slope stability analysis with non-circular failure surface

When analyze the stability of slopes, traditional methods often use suppose that the failure surface is circular or other typical functions. But because of complicated surroundings, these suppose only fit for some special questions. So this paper used GAs to search the non-circular critical failure surface, got a new optimization method for soil slopes, which is a global optimal algorithm with good character and don't depends on the shapes of slopes and the function's type.
