摘　　要：为了研究向家坝一期施工导流期间的通航条件,对该期间的河道流场进行了二维数值模拟研究。结果表明:随着流量的增加和水位的升高,通航水流条件逐渐变差,当流量超过某一值之后应当禁航。为船舶的安全航行提供了依据。In order to study Xiangjiaba′s navigable conditions during the construction phase,this article simulates the two-dimensional river flow field during the diversion construction,the result of which shows that with the increase of flow and the rising water,the navigable flow conditions turns poor gradually;When the flow rate exceeds a certain value,the navigation should be suspended.It may serve as a basis for the safe navigation of ships.
