In cases where the sheet pilling is allowed, when great retaining heights have to be achieved a combined quay wall structure is normally used. This structure consists of a sheet pile wall, a relieving platform, an anchor and a pile foundation system. The content of the present MSc thesis is divided into two major parts. The first part (Part A0 contains mostly hand calculations for the determination of the loads and for the analysis of the sheet pile wall, while on the second part (Part B) advanced computer programs will be used for the same purpose. A parametric analysis of seven different quay walls is investigated, for various loading combinations of given loads. In details, three different depths and two different widths of the relieving platform were investigated. In addition a quay wall combined only from sheet piles, without a relieving platform is also analysed. 1)The sheet pile wall, in Part A, is analysed by three different approaching theories of Blum. The fixity of the end point of the sheet piling is considered once as completely free and in the other two as fully fixed. Graphs concerning the effect of the various dimensions of the relieving platform, the embedded depth and the anchor force are produced. 2)In the Elastic Supported Beam theory (Msheet) analysis the ground is simulated according to a more advanced model. According to that theory, the Sheet Pile Wall is schematised as a beam on an elastic foundation, where the ground is simulated by a set of uncoupled elasto-plastic springs. 3)In Part B, the Finite Elements Method. PLAXIS created from Plaxis is used for that purpose. This type of analysis is based on a model in which the behaviour of soil and structure are integrated. Through a parametric analysis and a financial assessment of a quay wall, the economic effects of the relieving platform separately on the sheet pile wall and on the whole structure is estimated.
