小砾山引水枢纽钱塘江河段含沙量分布的数值模拟分析

The Numerical Simulation Analysis of Qiantang River Section Sediment Concentration Distribution in Xiaoli Hill Water Diversion Project

根据萧山引水工程附近钱塘江河段的泥沙资料,采用水流泥沙数学模型,模拟引水工程河段近域的流场和泥沙场,进而分析引水口附近水域含沙量的分布特征,得出引水工程所在钱塘江河段典型断面潮位、流速及含沙量的关系,为解决从钱塘江引水后萧山区内河河道泥沙淤积问题提供了技术参考。

According to the sediment data of Qiantang river segment ,which is nearby the Xiaoshan water diversion project ,this essay uses flow and sediment mathematical model to simulate the flow field and sediment field of the water diversion project nearby this domain ,and analyzes the sediment concentration distribution characteristics of the waters near irrigating gate ,thus getting the relationship among tidemark , flow velocity and sediment concentration of the Qiantang river typical section about the water diversion project . This essay provides technical reference for solving Xiaoshan district river channel silting problem after getting waters from Qiantang river .
