断面水位流量关系受断面冲淤变化影响较大, 为定量分析断面固化后对断面水位流量关系的影响, 采用物理模型方法进行试验, 对断面进行固化, 推求不同放水条件下断面水位流量关系. 试验结果表明: 断面固化后, 在高中水位下断面水位流量关系较为稳定, 但低水位下其水位流量关系依旧较为散乱. 研究成果对于断面固化情况下水位流量关系的稳定性分析提供参考.
斷麵水位流量關繫受斷麵遲淤變化影響較大, 為定量分析斷麵固化後對斷麵水位流量關繫的影響, 採用物理模型方法進行試驗, 對斷麵進行固化, 推求不同放水條件下斷麵水位流量關繫. 試驗結果錶明: 斷麵固化後, 在高中水位下斷麵水位流量關繫較為穩定, 但低水位下其水位流量關繫依舊較為散亂. 研究成果對于斷麵固化情況下水位流量關繫的穩定性分析提供參攷.

The relationship between the water level and flow affect greater by changes of erosion;in order to quantitative analysis the impact after solid cross section on the relationship between water level and flow ,the test has carried out with physical model test method,to make cross section solid,Deriving the sectional water level and flow relationship under different drainage conditions.The results showed that:After curing section,at the high school level more stable relations section of water flow ,but the water level at low water flow relation-ship is still relatively scattered.Research results for the relationship between water level and flow conditions under section curing stability analysis provides reference.
