长沙综合枢纽三期施工导流及通航模型试验研究
Model test study on construction diversion and navigation condition in 3rd period of Changsha comprehensive junction
摘要
Abstract
According to the characteristics of the third phase of construction diversion,the river flood capacity and navigation flow conditions were studied by integrated physical model with the scale of 1:100.By analyzing the rising value of upstream water level,the flow field characteristics near the cofferdam and the flow velocity,three kinds of optimized schemes were proposed to increase the overflow width and adjust the direction of longitudinal cofferdam and water flow.Based on the characteristics of the third phase of construction diversion and the comparison of rising value of upstream water level between different construction diversion schemes,the recommended proposal which was conducive to the river flood and construction layout was obtained.Finally,the flow field analysis shows that the flow condition of the recommended proposal meets the requirements of navigation safety.关键词
