| Summary: | A new highway is under construction since few years to join the capital; Erbil city with many main towns connecting; in the plan to the northern boarders of the Iraqi Kurdistan Region. It is a double lane road constructed according to modern standards. It crosses many mountains, and two tunnels are already completed, one is almost completed and another one is abandoned: hitherto. The completed part of the highway reaches the Hareer town with some parts being under construction before and after the Shaqlawa town. Because parts of the Highway are not completed yet; therefore, those parts suffer from slope stability problems; mainly due to the drainage problems. Other completed parts; however, suffer also from slope stability problems; mainly due to steep slope road cuts and/ or irrelevant treatments for the road cuts. Among those unstable slopes, we have chosen six stations, which experienced the most severe failures. At those six stations, we have applied field method to estimate the possibility of failure following Bejerman’s method. We have found that the failure possibility is high in the station Nos. 1- 4, and is Low in the station Nos. 5 and 6. |
