Design and analysis of bracing system for junction of basement floor No. 1 and No. 2 of a foundation pit

According to the design example of a foundation pit, a method for design and analysis of bracing system for the junction of basement floor No. 1 and No. 2 is introduced. Meanwhile, the geotechnical FEM software Z_SOIL.PC 2013 is adopted to calculate the model by using 3D numerical analysis method. The results of the numerical analysis are compared with the measured ones, indicating the feasibility of the proposed design method. Finally, some experience of the project is summarized.
