摘 要: 分析了广州市康王路下穿流花湖隧道工程主体框架结构计算,结构采用以概率理论为基础的极限状态设计法,以可靠指标度量结构构件的可靠度,采用以分项系数的设计表达进行结构计算分析。结构构件根据承载力极限状态及正常使用极限状态的要求进行计算和验算。防水等级为一级,钢筋混凝土结构的最大裂缝宽度在荷载的标准组合并考虑长期效应组合的影响下求得,设计中采用外部全包防水,迎水面和背水面的允许值均为0.2 mm,并不得有贯穿裂缝。在结构荷载计算方面,考虑设防水位和低水位荷载工况。此外,介绍了此类框架结构设计的受力计算分析方法及主要结果,提出了施工中应注意的问题,为以后类似工程提供借鉴和参考。

Abstract: This paper analyzed the calculation on the main frame structure of Liuhua lake tunnel project beneath Kangwang road in Guangzhou city. The limit state design method based on probability theory, the reliability metric structure member reliability index and the design partial coefficients of the structure expression were used for structural calculations. Structural members should be calculated and checked according to the bearing capacity limit state and serviceability limit state requirements. The waterproof grade was at the first level, the maximum crack width of reinforced concrete structure was obtained under the standard combination of loads and considering the impact of long-term effect of the combination. In the design, the external waterproof was used, the allowed value of the surface and the back surface was 0.2 mm, and there should be no crack. In the calculation of structural load, the condition of the water level and low water level load should be considered. Moreover, this paper introduced the analysis and calculation methods and main results of these frame structure stress, and put forward the problems in the process of the construction, which could provide the references for the similar works in the future.
