Abstract

This study dealt with the achievement of a diaphragm wall anchored in deep excavations to protect and support the multilayer soil structure. In this research study a reference model was established then a parametric study was carried out. The final obtained model of the case study was of a good approximation to the reality (the inclinometric data of wall displacement). In the parametric study, several calculation parameters (discretisation and precisions) and geotechnical parameters (the interface, water pressure and the anchor system) were varied individually and finally compared from the anchored to the non anchored wall. It is evident from this study that the variation of the parameters in a reasonable interval has considerable effects of horizontal displacement and moments on the wall. In the end it was concluded that the use of numerical analysis procedures can provide more efficient and more economic geotechnical project design.
