| 摘 要： | 通过深孔弧形钢闸门的水弹性模型试验,对比分析深孔弧形闸门在不同运行工况下的时均应力状态及其变化规律.分析结果表明:深孔弧门在不同运行开度下的结构应力状态不同,其最大应力的位置可因开度变化而发生转移,不同弧门的应力状态及其变化规律既有共同性也有差异.

| Abstract: | Based on hydroelastic model tests on radial steel gates of deep discharge orifices,a comparative analysis was performed of time-averaged stress states of radial gates and the regularity of their variation under different operating conditions.The result shows that radial gates are in different structural stress states under different operating gatages,that the position of the maximum stress of radial gates changes with operating gatage,and that there are both similarities and differences between stress states and regularities of their variation of different radial gates. |

| Keywords: | deep discharge orifice radial gate stress state model study |
