For these design procedures limit state assumptions are made concerning the lateral earth pressures acting on the structure to determine the support system characteristics. No information with regard to the deformation of the soil adjacent to the structure can be provided. The objective of this thesis is to examine the finite element method of analysis as an alternative design tool which is adaptable to a wide range of situations. Finite element models are developed to investigate the influence of the plastic flow rule, wall friction and the soil type on the behaviour of a cantilever support system. Subsequently, the effect of wall stiffness, prop stiffness and the application of prop loads on the performance of a multiple level support system is examined. The results from these studies focus on wall displacements, lateral earth pressures, bending moments, plastic strain patterns and surface settlements behind the wall. The investigation provides extensive information about the entire soil-structure interaction of the system. This potential of the finite element method can be used in the optimization of support system design.","abstract_html":"The design of lateral support systems, in the context of surface excavations, are usually done using conventional (classical) methods of analysis.
