通过对施工过程中的单壁有底钢套箱进行有限元分析,研究钢套箱整体结构的受力特点,对钢套箱结构进行优化设计,使得在保证安全施工的同时,钢套箱的受力状况有明显改善,且用钢量减少,研究成果已成功地应用于本工程其他套箱设计中,取得极为显著的经济效益,可为今后类似工程钢套箱设计和施工计算提供参考。 Through the finite element analysis of the single-wall steel box during the construction process, the force characteristics of the overall structure of the steel box are studied. The steel box structure is optimized so that the safety of steel box The stress condition has been significantly improved and the amount of steel used has been reduced. The research results have been successfully applied to the design of other quayside of this project, which has achieved extremely significant economic benefits and can provide reference for the design and construction calculation of similar steel box covers in the future.
