| Abstract: | Recently,large cylindrical underground structures have been widely used in underground projects,because this type of structures could take the mechanical advantages of the foundations pits.In this study,the design and analysis method for a cylindrical cistern project with 14m in depths and constructed with diaphragm walls of no buttress or ring beams is presented.To consider the 3D effects of the cylindrical diaphragm wall,three different methods are examined in this study.The results indicated that the 2D ... |
