| 本文对浙江省曹娥江挡潮泄洪闸双拱型钢管结构闸门在涌潮荷载下的承重结构进行了静力和反复加载的缩尺模型试验。静力试验数据分析表明，双拱型钢管结构闸门的承重结构主要受力构件为正拱、反拱和弦杆，它们组成了共同受力系统，以承受轴向应力为主，沿跨度方向受力均匀，材料的利用率高，说明其形体是合理的。反复加载试验模拟了钱塘江涌潮荷载，考察了在设计使用寿命期内双拱型钢管结构闸门承重结构在涌潮荷载反复作用下的受力特性，论证了承重结构在设计使用寿命期内不会发生疲劳破坏。 |
| 英文摘要: |
| The model test on a double arch gate with tubular structure working both as tidal barrage and flood control gate is carried out to demonstrate the reasonability and reliability of the structure. The static test result shows that the main arch, the chord and invert arch work together forming a rigid system to bear the forces transfer from the plate of the gate. The forces acting on the tubular member is axial and the loading distribution along the span is uniform. It verifies the design of the gate is reasonable and the utilization rate of material is high. The cyclic loading test for simulating the long term operation shows that the fatigue problem will not occur in the designed working period. |
