感潮河口水闸口门防冲技术探讨

Discussion on erosion control techniques of the exit at tidal sluices

感潮河口水闸闸下多为软基,口门冲刷问题突出。该文采用物理模型和数值模拟相结合的方法,探讨了感潮河口水闸无翼墙式新型消能工技术的可行性。研究表明,该技术与常规水闸相比,简化了翼墙和防冲槽设计,可以使闸下水流充分消能、有效减轻闸下冲刷,可为类似工程设计和应用提供相应参考。

There are always soft foundation under tidal sluices, so scour problems at the exit are obvious. Using physical model and numerical simulation methods, the new technology of energy dissipation of tidal sluices without wing wall is discussed. The study shows that, compared with conventional sluices, this new technology simplifies the design of wing wall and anti-scour trench, has high energy dissipation and alleviates the erosion problem effectively. It also provides a reference for design and application of similar projects.
