Abstract

Using the Soil Nailing due to its numerous advantages, the traditional approach is to stabilize the excavation walls fitted. Due to the different behavior of marl soils in short and long-term and fundamental role of friction between soil cement grout around the walls were nailed, In this study, tensile strength and creep behavior of soil nails to maintain green marl are discussed. Therefore, the number 6 nails diameter of 11 cm and a length of 4 m in vertical and 2 achieve the same as the horizontal at an angle of 15 degrees to the horizon scale has been constructed and the effect of Drillings Type on the tensile strength and creep behavior were investigated. the results indicates 20 to 25% increasing in tensile strength of nails in vertical mode and 15% increasing in a horizontal mode implemented with non-smooth drill compared to smooth drill.
