摘要
为了验证新疆某工程溢流表孔设计的合理性,通过水工模型试验对溢流表孔的堰面曲线、斜坡、反弧段的设计体型进行验证。结果:溢流表孔的泄流能力略小于设计泄流能力,沿线均为正压,仅在出口处出现负压,但负压值较小,不会出现空蚀破坏;挑流消能效果较好,冲涮坑离挑流鼻坎较远不会危及鼻坎的安全;成果已被设计采用。
In order to examine the design of surface spillways for a project in Xinjiang, hydraulic model test was conducted to check the weir surface curve, slope, reverse arch section of spillways. The results of test demonstrate that the discharge capacity is slightly less than the design value; minor negative pressure only occurs at the outlet without cavitation damage; ski-jump energy dissipater renders good effects with the scouring pit far from the deflector bucket. The results of test was adopted by design.
