The aim of this thesis was simplified design of diaphragm wall affected by excavation from both sides. This wall is a part of temporary shaft that serves for exchange of tunnel boring machines and at the same time it is a permanent structure of an adjacent metro station. Part of the thesis deals with description of construction sequence of diaphragm walls, excavation of the shaft, excavation of the adjacent metro station and following construction of metro tubes and backfilling of the shaft. Inseparable part of the thesis is assessment of geological conditions and geotechnical parameters. Furthermore, a study on temperature loads on struts was carried out and the results of the study were used for design of the struts. To fulfil the requirements of the assignment several models of the shaft structure and adjacent metro station were built in program Plaxis and one model of the diaphragm wall of the shaft was created in program Geo5. The model outputs were subsequently compared to each other. Furthermore a model of lateral support frame was created in program Scia Engineer. Outputs from programs Plaxis and Scia Engineer were used as a basis for design checks of the structure. The design checks were done according to Eurocodes. The diaphragm wall and the lateral support frame were designed to support the loads considered in this thesis. In order to simplify the calculation variable loads from construction machines were not considered and the only variable load considered was the temperature load on struts. Lateral support frame was also designed to accidental load – loss of a strut.
