Abstract
The aim of this article is to establish guidelines for the calculation of log-crib walls stability, popularly known like Krainer walls. These structures combine both engineered and biological features and that is the reason why they require stability calculation. The existing information about walls is large but not specific about this technique. It is proposed a method which determines admissible forces between soil and constructive materials. These stability calculations consider security against sliding, overturning stability, resistance to bending and anchorage and union checks. The bioengineering restoration has to be improved against less environmentally sensitive techniques (rock wall or concrete) as it achieves bank stabilization as well as the conservation and maintenance of local vegetation. Thereby, it is necessary to establish calculation criteria to ensure its proper functioning.
