Conclusions

  1. 1.

    The analytical method presented above for determining the necessary anchoring force T for a given factor of safety, based on the polygon of forces method, permits a rather rapid detemination of the magnitude and direction of this force.

  2. 2.

    Using the functions obtained, we can determine by trial and error the value of the factor of safety against sliding of a block in a natural (unprotected) state.

  3. 3.

    Programming of the analytical solution obtained on a digital computer greatly reduces the time necessary for performing the calculations.
