| Abstract: | In the design and construction of super foundation pits, the athwart construction method is economical and effective. Aiming at a practical project, the super foundation pit for the Business and Trade Center of the Minhang District, Shanghai, the paper makes a FEM analogue analysis. The changing law of internal forces and the displacement of the underground continuous wall are anticipated. Therefore the paper may serve as a reference for the design, construction, and inspection of the athwart construction of other super foundation pits. |
