摘要
闸站合建工程在闸行使通航功能时,导流墩附近出现回旋区、斜流等复杂水力现象,影响着船只通航安全性。采用物理模型试验方法对不同方案下的导流墩进行试验,并对试验结果进行分析。试验在自排工况下,设计了6种不同长度、不同开孔参数的导流墩方案对通航口门区水力特性进行研究。试验结果表明:方案4中导流墩适宜长度及开孔参数,可减小导流墩附近回旋区范围及墩头前斜流区,改善口门区水流流态,为通航提供了良好的水流条件,为类似闸站工程通航口门区整流方案提供参考。
Complex hydraulic phenomena, such as circular area and oblique flow, occur near diversion piers in the joint construction of station and pumping station, which affects the navigation safety of ships. The physical model test method was used to test the piers under different schemes, and the test results were analyzed. Under the self-discharging condition, 6 kinds of piers with different length and different opening parameters were designed to study the hydraulic characteristics of navigable port area. The test results showed that the suitable length and opening parameters of the diversion pier in plan 4 could reduce the circle area around the diversion pier and the inclined flow area before the pier head, improve the flow pattern in the mouth area, provide favorable flow conditions for navigation, and provide reference for the rectification scheme of navigable mouth area of similar sluice station engineering.
