A Study of Network Roads Landslides and Their Stabilization Methods in Fahs Anjra Province: North of Morocco

Landslides affect roads and transportation networks in Fahs-Anjara in Northern Morocco, which constitutes a major economic, human, and service dilemma. In order to assess this latter, we are eager to perform a detailed analytical study of the main contributing factors to landslides. To achieve this objective, we collected 108 landslides. In addition, we classified the contributing factors into five main sections (hydrology, hydrogeology, geology, geometry of the ground, and topography). Afterward, we entered the input data by using an advanced statistical program called SPSS to obtain an accurate result. Consequently, we classified our landslide types under five categories which are: 1-Debris flow, 2-solifluction flow, 3-circular slide, 4-planar slide, and 5-pavement cracks and irregularities in the longitudinal profile of roads. Our findings showed that hydrology factors are one of the most important triggers of landslides in the province of Fahs-Angara. The results of our study proved that circular landslides are the most common type of landslide in this area. Finally, our suggestive solution to stabilize landslides in this region is the appropriate surface water drainage of hills or roads. The goals of this research article aim to help civil engineers, geotechnics, designers, and decision-makers to perform a better planning and implementation of the road and transport networks, as well as to avoid the dangers and big loss resulting from the occurrence of landslides.
