| Abstract: | The staged construction mechanics of the steel sheet pile retaining structure for a cofferdam project are numerically simulated using 3D FEM incremental computing method.The lateral displacement and bending moment of the steel sheet pile,the brace bending moment and the steel pipe axial force are emphatically studied.The results indicate that the design of the steel sheet pile retaining structure and the construction scheme of the cofferdam engineering are feasibly in theory. |
