电站不同下泄流量下游锚泊区停泊条件分析

Analysis of anchored conditions on downstream anchoring region based on different discharge flow in hydropower station

电站泄洪、发电时下泄水流沿通航建筑物引航道导航墙进入主河道后过流断面骤增,水流脱壁后发生斜向流动,在引航道口门区形成回流。若枢纽下游航道锚泊区距口门区较近,则一定条件下回流将对锚泊区内船舶停泊条件带来不利影响。以景洪水电站为例,采用实船试验的方法,研究电站不同泄流量下升船机下游锚泊区水流条件的变化情况及相应的船舶待机停泊条件,得出不同下泄流量下船舶系缆力特性以及船舶合理的待机停靠位置。

The downstream mooting area of Jinghong hydropower station is close to the downstream approach channel entrance gate.The discharge and power generation of the power station will adversely affect the berthing conditions of the downstream standby ships.We take the method of trail voyage testing to study the downstream mooring area of the anchor parking conditions in the Jinghong hydropower station under different discharge volume.The characteristics of the mooting force and the reasonable standby position of ships are obtained under the different discharge volume.
