Abstract :

     In the present paper, a landslide and its stabilization is studied on a slope of Tabriz Northern Freeway. This landslide is a large scale one, and as the study zone has a sliding potential so that its study is quite necessary. The analysis of landslide has been performed using STABL software. The way of obtaining the critical slope for land slide amongst different sections and determining a successful and optimum stability method for each section with sliding possibility, is very important. In the slope under study this has been done using radial sections’ method which shows that the slide does not occur in the direction of the largest slope when there are irregularities in ground. The study of methods of stabilization of sections with sliding potential and their economical studies is of particular importance. It is quite possible that a local stabilization for a land- slide, may stabilize the while sliding zong. Knowledge of ways of occurrence of different landslides and study of their proper stabilization methods for any particular land- slide is the base of landslide studies. Also the stabilization analysis will be important after performing the stabilization method to show that if the stabilization method is significant.
