| Abstract: | Chi-gang metro station is a two-floor reinforced concrete frame. The cross span of the floor is 16.3m, the allowed load on the floor is 40 kN/m2. During the construction of shield tunnel, the real load applied on the floor will be 50~60 kN/m2. To ensure the safety of the metro station, the floor is strengthened with steel braces temporarily. This paper deals with the mechanical analysis and fixing of the temporary braces. |
