Abstract :The stability problems observed in the cut section during the highway construction works in Aktaş Village of Siirt Province (eastern Turkey) were analysed by the limit equilibrium and finite element methods, and factor of safety and collapse surfaces were determined. This section is of critical importance since similar high cut sections are frewuently encountered in the study area. In the light of field investigations, laboratory and literature shear strength parameters for analyses were obtained. In stability problems, it is difficult to determine the location and shape of the sliding surface. On the model reflecting the current situation, collapse surfaces were detected and calculations for safety analysis were made by using Plaxis V24 2D, which is based on the finite element method, and Slide2, which is based on the limit equilibrium method. Although the two methods seem compatible in terms of factor of safety, factor of safety obtained with the finite element method are lower. In addition, it has been determined that the finite element method gives more positive and reliable results in terms of determining the locations of failure zones in the soil and obtaining stress deformation curves.
