Kranz and Broms’ methods are briefly reviewed and it is shown that they are equivalent, under the same conditions, giving the same results. Broms’ method is applied to a relatively wide range of cases of anchored retaining walls with two anchor levels, considering different anchor inclinations, locations of anchor heads, embedded lengths and soil strength parameters. The method is used to determine the length of the top anchor level needed to ensure overall stability, for a given length of the bottom anchor level. Results are compared with traditional simplified procedures. It is shown that for certain cases these simplified procedures does not ensure overall stability.
