摘要：The navigation influenced by extension project of a sluice was researched in this paper. This sluice connected the inland river and outer river, and the hydraulic characteristics beside it were significant for ships' passages. The test in this paper was conducted for simulating the flow patterns and hydraulic characteristics around this sluice. According to the test results, the flow velocities and flow patterns around approach channels of the inland river and the outer river in various conditions are given in this paper, including the maximum lateral flow velocity and the maximum reserved flow velocity. These data provided scientific bases for safe operation of the sluice and navigation channels. In addition, a guide wall was proposed to effectively reduce the lateral flow velocity.
