摘要
分析总结了山区河流通航建筑物引航道与河流主航道夹角形成的因素。通过概化物理模型和船模航行试验,研究了船闸布置在弯道凸岸以及引航道与河道斜交布置2种条件下,引航道与河流主航道不同夹角时,口门区和连接段的通航条件。试验表明,当船闸布置在弯道凸岸附近,河道流速为1.5～2.0 m/s时,转弯夹角宜小于20°;当引航道与河道斜向布置,河道流速为1.5 m/s时,夹角宜小于等于25°,当河道流速为2.0～2.5 m/s时,夹角宜小于等于20°。
The forming factors of angle between the approach channel of the navigation structures and the main channel in mountain stream are summarized. By generalizing the physical model and ship model test, considering two layouts of ship lock,including ship lock at the bend convex hank and approach channel obliquely across a river,the navigation conditions in the entrance area and the connecting section under the different angles between the approach channel and the main channel are studied. The results show： when the ship lock is at the bend convex bank, flow velocity is 1.5 - 2.0 m/s, the swerving angle is recommended to take the value of less than 20°; when the approach channel obliquely across a river, the flow velocity is 1.5 m/s, the angle should less than or equal to 25°, the flow velocity is 2.0- 2.5 m/s,the angle should less than or equal to 20°.
