Setback distance between natural slope and building along the RN8 in Algeria

Abstract

The objective of this study is to determinate the required distances between the natural slopes and the buildings located nearly to these slopes. This approach permits to determining the distance between a building and the crest of a natural slope. The analysis of this case uses the geotechnical engineering and the results are applied during the design of the master plan by the town planners and the engineers of the transport and pavement administration. This study is limited to only the stability of natural slopes and the phenomenon of erosion is not taken into account. The work begins by to present the context of study and the reinforcement works required by the administration of pavement and transport. Then, the limit equilibrium method is used for to obtain the minimal distance, limited by the crest of slope and the building. This distance is verified by simulations and compared to the distance corresponding to the beginning of the first plastification zones. The checking of plastification is carried out by the finite elements method. The work terminates by the presentation of the obtained graphics on the setback distance, and by the recommendations on the implantation of buildings. © Springer-Verlag Berlin Heidelberg 2013.
