府谷黄河桥悬沙冲淤数值模拟
Numerical Modeling on Scouring and Silting of Suspended Sediment in Fugu Yellow River Bridge
【摘要】 本文运用不平衡输沙原理对位于黄河中游的府谷铁路大桥进行了二维悬移质泥沙冲淤的数值模拟。数值计算结果与模型试验实测资料吻合较好。
【Abstract】 In this paper,based upon the principle of unequilibrium sedimenttransport,the numerical modeling have been fulfilled on two-dimensionalscouring and silting of the suspended sediment in Fugu railway bridge situa-ted in the middle reaches of the Yellow River.The numerical results arequite consistent with the test data of the hydraulic model experiment.
