Abstract

The Mediterranean Bypass road in the North of Morocco is frequently subject to landslides. In this paper, the case of Jebha is studied to deduce trigger factors and then to suggest reinforcement solutions. Between the PK5+300 and PK6+000, a slip of the slope is occurred even if it was stabilized during project work. To analyse soil consistency, geotechnical recognition is established. Based on material characteristics, slope mechanism model is done using 2D finite elements modelling using Plaxis software. Results show that vulnerable geotechnical nature of materials, rugged topography and saturated soil in El Jebha cause slippage. Therefore, to ensure safe traffic flow comfortably, solutions of reinforcement are proposed.
