| 摘要: |
| 基于可靠度原理，建立了钢闸门结构模糊刚度可靠度分析的极限状态方程，分析了荷载和抗力的统计参数。在不同荷载组合的情况下，对水工钢闸门的模糊刚度可靠指标进行了计算，计算结果表明，露顶门的模糊刚度可靠指标大于潜孔门。 |

| Abstract: |
| Based on the principle of reliability, a limit state equation for fuzzy stiffness reliability analysis of hydraulic steel gate structures is established, and loads and resistance statistical data are analyzed. The fuzzy stiffness reliabilities of hydraulic steel gate structures with different loads combination are calculated. Calculation results show that the fuzzy stiffness reliability indices of the exposed-top gates are higher than those of the submerged gates. |
