dc.description.abstractThis thesis aims to study the various parameters that may affect the lateral pressure on propped deep excavations. The parametric studies were carried out using numerical modeling based on the finite element method. Extensive parametric studies were performed to explore the effect of soil parameters and the arrangement and the properties of the retaining system on the distribution of lateral pressure. The results of numerical modeling are generally comparable to those obtained with classical design approaches using the apparent pressure diagrams that were developed by Peck (1969) and Tschebotarioff (1973). In the case of small thicknesses as well as small penetration depths, the lower struts reveal higher prop forces. According to the configuration of the excavation, the prestressing force may vary from one prop to another. Finally, some practical recommendations are given for geotechnical design of supported deep excavations.fr
