| Abstract: | The author idealizes the hole wall surrounded by multi stratum soils into a cylindrical hole subjected to body forces,uniform pressure acting on the ground and hydraulic pressure acting on cylindrical surface.Applying the theory of elasticity and yield criterion of plasticity,the author obtains the unyielding conditions,which have been used in practice,for the side wall of pre bored holes. |

| Keywords: | unyielding conditions for soils yield criterion elastic solutions |
