Stability of the Walls in Nails Soil
Developed as from the seventies, the nailing of the soils is a technique, which makes it possible to carry out a retaining wall of excavation by using the soil in place and installing the passive bars called nails. The main object of this work is to study the stability of the walls in soil nailed lived overall rupture facing-soil-nail. In order to find the mechanism or the mechanical model most unstable. Give a general aspect to our studies; we also studied a title comparative the classical circular failure model. We have repeatedly determined for each case the maximum shear soil force in the nails Tm. The most unfavourable mechanism (less stable) among all the mechanisms is that for which, the shear force Tm reached a maximum. Another analysis of the stability of wall in nailed soil was made by means of the software Geo4 and compared with the kinematics method.
