平面二维数模研究闸下淤积的缺陷探讨

Discussion on the Limits of Two-dimensional Plane Model for Sedimentation Downstream of Sluice

以姚江大闸和武障河闸为例,对河口水域建闸后的闸下淤积的机理进行了研究。通过应用二维悬沙模型的模拟计算,分析了数学模型在模拟近闸段的淤积时存在的缺陷,对产生问题的原因进行了初步探讨。由于闸下淤积问题存在明显的时空性和区域性特征,应积极研究解决措施。

This paper focuses on sluice sedimentation mechanism after construction of river gate at estuarine areas with case studies of the Yao River and Wuzhang River sluices.2D suspended sediment model is used in this study to simulate and calculate,and the limits of the model in the simulation of the sedimentation near the sluice are also analyzed in the paper.The causes for the problem are preliminarily discussed.Because the sluice sedimentation has special and temporal characteristics,it is necessary to study the countermeasures to solve the problem.
