| 中文摘要: |
| 裕溪一线船闸扩容改造工程首次将三角闸门的应用口门宽度提高至34 m。为提高船闸的运行效率、充分发挥三角闸门动水启闭的优势，开展了大型三角闸门门缝输水运用条件试验研究。以三角闸门的水动力特性和船舶停泊安全为依据，研究提出裕溪新船闸大型三角闸门门缝输水的运用条件：1）三角闸门采用门缝输水应尽可能在1 m水头差以内开启；2）闸门开度应控制在1 m以内；3）随着水头差减小闸门开度可进一步增大。 |

| The expansion and reconstruction project of the Yuxi first-line ship lock increased the width of the sector gate to 34 m for the first time. To improve the operation efficiency of the ship lock and give full play to the advantages of the opening and closing of the dynamic water of the sector gate,an experimental study on the water conveyance condition of the large sector gate joint is carried out. Based on the hydrodynamic characteristics of the sector gate and the safety of ship berthing,the study puts forward the operating conditions of the large triangular gate of the Yuxi new ship lock. The conditions are as follows:1）The water conveyance of the sector gate should be opened within 1 m head difference as far as possible. 2）The opening degree of the gate should be controlled within 1 m. 3）With the decrease of the head difference,the opening degree of the gate can be further increased. |
