通过江苏、上海等地 10余座闸站合建工程的物理模型试验成果分析 ,总结出闸站合建枢纽的三种主要布置型式 ,即平面对称布置、平面不对称布置和立面分层布置 .在各类整流措施中 ,闸站结合部加设导流墙和泵站前池加设潜墩 ,可以有效地改善由于主流偏斜所诱发的回流、螺旋流等不良流态 Through the analysis of physical model test results of more than 10 sluice station construction projects in Jiangsu and Shanghai, three main layout types of the hub of the sluice station are summarized: plane symmetrical arrangement, plane asymmetrical arrangement and elevation arrangement In all kinds of rectification measures, the addition of a diversion wall at the junction of gate stations and the addition of a submarine pier at the forebay of the pump station can effectively improve the adverse flow regimes such as backflow and spiral flow induced by the mainstream deflections
