地下室顶板在上有压重时的加固措施及承载性能分析

Reinforcement Measures and Bearing Capacity Analysis of Basement Roof Under Weight Load

针对施工现场地下室顶板在上有压重时的加固问题,从不同荷载类型的取值出发,研究了钢管排架回撑、型钢回撑、混凝土柱回撑,以及永久结构增强等措施的优缺点,并分析了在车辆等效均布荷载作用下不同加固措施的承载性能,为此提出了不同荷载类型下的加固措施选择,为地下室顶板选择合理的加固方式提供参考。

Aiming at the reinforcement of basement roof in construction site under weight load,based on different load types,the advantages and disadvantages of steel pipe bent brace,section steel back brace,concrete column back brace and permanent structure reinforcement are studied,the bearing capacity of different reinforcement measures under equivalent uniform vehicle load is also analyzed,and the selection of reinforcement measures under different load types is put forward to provide a reference for choosing a reasonable reinforcement method for basement roof.
