文章建立了三角门船闸物理模型，通过物理模型试验研究了开通闸运行时闸室、引航道的水动力条件以及闸门启闭机的受力。在此基础上，提出了开通闸运行的判别方法，确定了该船闸宜进行开通闸运行的临界上下游水位差。研究结果表明，不同来流条件下，当上下游水位差处于-0.35~0.37 m，且不超过设计水位时，闸室和引航道主流波动较小，流速对开通闸运行影响不大，且船闸启闭机受力不超过设计值，焦港船闸可进行开通闸运用。

A physical model of Jiaogang ship lock was established in this paper, and the flow condition in lock chamber and approach channel was studied by the model. On this basis, a new method to confirm the critical condi-tions of ship lock running as an open channel was put forward. And the experiment results indicate that the main flow oscillates less and stress on hoist does not exceed the designed value when the water level difference between upstream and downstream is between-0.35 meter and 0.37 meter. Under the critical water level conditions, the Jiao-gang ship lock sluice gate can be hoisted safely.
