| Abstract: | It requires a lot of temporary structures during the bridge construction, for these temporary structures,if we invest too much it will cause waste. If we not, satety accidents will be caused. This paper introduces the definition, the characteristics and the existing main problems of the temporary structures, discusses the problems when the allowable stress method used in the design of temporary structures, which can provide the certain basis for the temporary structures design. |
