新疆宽浅变迁河流动床模型验证——以呼图壁河模型为例

以呼图壁河动床模型验证为例,分析"自相似"动床模型验证中涉及到的模型砂选取、试验加砂控制、模型验证指标的确定等方面的问题.通过对呼图壁河动床模型与原型河段的水面线、河床变迁范围、典型断面的冲淤深度比较,模型结果和实际基本一致,说明呼图壁河动床模型设计和模型布置合理,同时为新疆宽浅变迁河流的动床模型设计和验证提供参考.

Verification of Movable Bed Model of Broad-Shallow Shifting Reach in Sinkiang Region:Taking the Model of Hutubi River for Example

Taking the model of Hutubi River for example,the problems of verification of the self-simulation movable bed model,such as the model sand,the model inlet controlling and the verification standard,were studied.By the verification of water level,the shifting range and the scour depth of the type section,the result of the model was consistent with that of the archetype river.The movable bed model design of Hutubi river is feasible,and can be the reference for the movable bed model design of the broad-shallow shifting reach in Sinkiang region.
