| 摘 要： | 考虑平面钢闸门主梁的破坏特点，将主梁破坏形式分为弯曲、剪切和弯剪复合破坏３种，分别进行其可靠度校准分析，得到不同的可靠度。然后，运用结构体系可靠度计算方法，得到主梁体系可靠度，当抗力为正态分布时为３．５３９；当抗力为对数正态分布时为３．９４。

| Abstract: | In consideration of the destructive characteristics of the primary beam of plain steel gate,its destruction is divided into three types:bending,shearing and the combination of bending and shearing.Their reliability check analyses have been made to gain the different reliabilities. Then, the calculation method of the structural system's reliability is used to calculate the reliability of the structural system. When the resisting force is in the normal distribution, its reliability is 3.539.When the resistintg force is in the logarithm normal distribution, its reliability is 3.94. |
