Landslides are present on all continents playing important role in the continual evolution of this type of similar geohazard. They constitute a serious hazard in many areas of the world. Most of Iran's land is covered by mountainous areas. One of The dangers that always threaten these areas are the instabilities of the slopes. The occurrence of this phenomenon causes a lot of damage to the cultivated lands every year Human enters. Among these, one of the most dangerous domain instabilities Landslide is a phenomenon. Kurdistan province and within the study area (Bane city) as a part of the province, is one of the areas that due to the conditions geological, topographical, and climatic specifics along with the human factor, in some places, is prone to landslides. The most important of these landslides can be found in Gardaneh Khan, Savan, Sabdlo, and Dar. Finally, an ALUT is pointed out as an indicator. Therefore, identifying the process of landslides is necessary to identify, investigate and determine the causes of landslides at the level of the regions of the country it arrives in this study, the paper also discussed the manifestation, causes, and effect of landslides. For geotechnical analysis, samples were collected from the landslide site and subjected to the following tests: natural soil moisture content, specific gravity, relative density, shear strength, and compaction permeability. Adjacent slopes of still intact slides were also analyzed using Plaxis 2D to determine their safety factor. Both the geotechnical laboratory results and the Plaxis 2D results show that without the improvement of the infinite slope condition using the method recommended in this paper, another landslide will inevitably occur. Several of the methods recommended include cutting back of slope to reduce its gradient, reinforcements, soil nailing as well as anchors and retaining structures. تفاصيل المقالة
