| 中文摘要: |
| 八堡双线船闸为京杭运河沟通钱塘江第二通道的关键性节点工程，其上下游引航道均采用共用引航道的布置形式。为保障双线船闸运行时的船舶过闸安全，通过实船试验及水力学观测对引航道水流条件及船舶停泊条件等参数进行测量，并对船闸通航安全进行分析。结果表明：引航道水面波动在-0.29~0.38 m，不会导致船舶擦底现象发生；双线船闸同时充泄水时，引航道内的最大流速为0.44 m/s，船闸人字门处最大瞬时反向水头为0.143 m，船舶最大系缆力为5.74 kN，均满足规范要求；船闸单线运行时，对另一侧船闸的船舶进出闸不造成影响。 |

| The Babao double-lane ship lock is a key node project for the Beijing-Hangzhou Canal to connect the second channel of the Qiantang River.Its upstream and downstream approach channels are arranged in a shared approach channel.To ensure the safety of ships passing through the ship lock when the double-lane ship lock is operating,we measure parameters such as water flow conditions in the approach channel and ship berthing conditions through real ship tests and hydraulic observations,and analyze the navigation safety of the ship lock.The results show that the water surface in the approach channel fluctuates between -0.29 m and 0.38 m,which will not cause the ship to rub against the bottom.When the double-lane ship lock is filled and discharged at the same time,the maximum flow velocity in the approach channel is 0.44 m/s,the maximum instantaneous reverse water head at the ship lock herringbone gate is 0.143 m,and the maximum mooring force of the ship is 5.74 kN,both of which meet the code requirements.When the ship lock operates in a single line,it will not affect the entry and exit of ships on the other side of the ship lock. |
