高拱坝泄洪中孔弧形闸门振动试验研究

在大量模型材料试验研究的基础上，选用增强工程塑料制作闸门模型，使之同时满足水流相似和结构相似条件的要求，从而实现了通过水工模型试验直接测量深水闸门在实验运行过程中的振动性态以及闸门结构的应力状态，为水工钢闸门振动试验技术的改进作了一点有益的尝试。文中就某高拱坝泄洪中孔弧形闸门在不同工况下的振动情况给出了有关的试验结果。

Experimental study of radial gate vibration in spillway of Dongfeng arch dam hydraulic power station in Wu River

The water flow-induced steel gate vibration is an important research problem in hydraulicengineering. To measure the vibration characteristics and stress of the gate under the flow-induced vibration,the authors must achieve the model simulation to prototype in water flow andstructure. Because of the limit of the model simulation law and used materials,the authors havenever done so before, In this paper, the authors have used the reinforced plastic as the modelmaterial and solved the above problem through a large number of researches of the model materialcharacteristics and the model simulation laws. And using this experimental model, the authorshave measured the stress conditions and vibration characteristics of the vibrated gate under manyoperating conditions of the steel gate. This paper has initiated a new way to improve the researchlevel of gate vibration experiments in hydraulic engineering.
