主动式钩连体防冲促淤效果研究

Deceleration and accretion promotion effect of active hook structure

主动式钩连体作为一种新型的消能护滩结构,在长江深水航道一期工程中进行了首次应用。通过动床、清水冲刷试验,对主动式钩连体的防冲促淤特性进行研究,并分析工程实施前后的观测数据。试验和观测结果表明,该结构守护范围内泥沙淤积明显,并对其周边有一定的掩护作用。

As a new type of energy dissipation and protection structure, the active hook is used for the first time in the first phase of the Yangtze River deepwater channel project. This paper studies the charaeterislies ofteeeleration and accretion promotion by the movable bed and erosion experiment and analyzes the observation data data before and after the project implementation.Experimental and observational resulls show that sediment deposition is obvious within the scope of protection and the structure is able to cover a certain range of its surroundings.
