摘要
根据《水利水电工程钢闸门设计规范》、结构可靠度理论及弧形钢闸门空间框架的失效模式，提出其空间框架体系可靠度计算的串联模型及计算方法；在对钢闸门基本构件可靠度研究的基础上，应用该串联模型及计算方法，分析了弧形钢闸门空间框架体系的可靠度。结果表明：按现行规范设计的双支臂弧形钢闸门空间框架体系的可靠度指标最低为３．４（１６Ｍｎ钢）或３．２（３号钢），比基本构件的可靠度指标小０．８５，与建筑《设计标准》的可靠度指标一致。
In this paper,in tandem mode and calculation procedure of the reliability calculation of the steel arch gate space frame system are put forward according to “Steel Arch Gate Design Criterion of Hydraulic and Hydroelectric Engineering”,the Theory of Structural Reliability and Failure Mode of Steel Arch Gates Space frame; On the basis of the reliability research on Steel Arch Gates basic elements,reliability of steel arch gates space frame is analysed by means of in tandem model and its caculation method.The result indicates that the reliabilitys minimum index of the double butress steel arch gate designed according to the regulatory specifications is 3.4(16Mn Steel) or 3.2(No.3 steel),which is 0.85 smaller than the reliability index of the basic elements.The minimum index is in agreement with the reliability index of the architectural “Design Creterion”.
