Abstract

One of the most important problems and challenges in civil engineering is constructing structures, protecting excavation and the building in their surrounding and stabilizing embankments. Non-observing proper methods for protecting deeps and also constructing slopes will lead to irreparable damage and the risks resulted from probable subsidence and reducing the bearing capacity and lateral displacements will cause cracks in neighbouring structures of deep has been Described by FHWA (1998).
Studying the nails behavior in marl and clay soils which are considered as fine-grained soils with different properties compared to grained soils are the subjects which has been considered less. High plastic properties, semi-saturation state, changing its behavior in long-term, very low grouting and other similar cases are among the problems which necessitates studying the nail function in these types of soils.
