  abstract = {{T}he goal of this paper is to document causes of the failure of stabilization measures undertaken for stabilizing a complex landslide threatening the {S}idi {R}ached viaduct in {C}onstantine, {A}lgeria. {S}ince the first instabilities, documented in 1910 during its construction, significant disturbances have been regularly observed on its eastern part and reinforcements carried out were only temporarily effective. {O}bserved disturbances are inherently related to the fact that the eastern abutment and the three subsequent piers are built on unstable {M}aastrichtian marls whereas the remainder of the viaduct rests on stable {T}uronian limestone. {T}he five main factors controlling the activation of the failure process are reviewed: (1) geomorphology, (2) geology, (3) human activities, (4) climate, and (5) seismicity. {D}ata interpretation of two inclinometer surveys carried out close to the eastern abutment shows that the unstable mass moves westward, towards the {R}humel gorges. {T}he main slip surface is located in the {M}aastrichtian schistose marl, at a depth ranging from about 8 m (west) to about 30 m (east). {T}his translational slide is associated with a settling phenomenon due to the petrophysical properties of the unstable marl.},
