Static and kinematic height limit of vertical slope

Abstract

In the present paper static and kinematic limit of vertical slope has been analyzed. An overview of literature is given. It is well know from Drucker-Prager paper (1952) that lower bound (static) is H=2c/γ where c and γ are cohesion and specific weight of soil respectively, while upper bound (kinematic) is H=4c/γ. Recently some attempt using numerical approach, mostly finite elements, have been published. In the paper all solutions will be analyzed, and an attempt of authors to improve them will be given.
