Features of landslide structures’ designing in emergency situations

Abstract

During the operation of the M-27 highway, a landslide became active on the km 56 + 680 section of the Tuapse district (Russia). As a result of the landslide masses displacement, the roadbed was destroyed and, as a result, traffic was restricted. In emergency situations, with the rocks’ continued displacements, it was necessary to develop the constructive solutions for the landslide structures in a short time. Engineering protection of roads on landslide slopes requires a detailed analysis of the source data, as well as a set of calculations to determine the designed structures’ strength and the slope’s stability. However, in emergency situations, it is often necessary to install the structures even with insufficient initial data based on a visual inspection of the site, as well as archival data. The article presents the results of a landslide site survey, as well as the results of modeling a slope with various combinations of loads. In addition, the constructive solutions of both priority measures and the main landslide control structures are presented.
