Abstract
Nailing system did not work in Rudsar town ship and course of use the new methods for real choice of this subject for analyzing point of nailing for investigation of the Rudsar township mountain side. In this project by attention to geothecnic character have with “Mahab Ghods “ office, in investigation with using of USA Standards (FHWA), nailed slope systems on the clay with high plasticity (HC) by 10 meters height, with help of nails by 15 degree angle, with help of steel mesh dimension 20*20 cm (WWM 20*20 cm), with give portion from nail design. However at start with help of present tables in FHWA. The surface amount of nail section is 700 mm2, horizontal step is 1.5 m, vertical step is 0.75 m and safety factor (FS) is controlled and the end, analyzing by FLAC software. First amounts of design sorts by complete analyzing. The specification of soil tests is complete from particular weight, shear resistance and etc. groundwater level is controlled. The results have shown the positive and acceptable effects of the nailing method in different angles, the details of which are fully presented in paragraphs 1 to 9 of the conclusion section of this research.
