河道允许不冲流速的取值对于河道断面设计和护坡型式的选择具有重要意义,在上海地区以往河道设计中,往往选用相关规范和参考书籍推荐的流速,缺乏很强的针对性。我处在进行长兴岛水系整治一期工程时,联合河海大学专门对允许不冲流速进行了物理模型试验和研究,得到较为可靠的结果,有效指导了工程设计工作。 The value of non-inflow velocity of river course is of great significance for the design of river sections and the choice of slope protection type. In the past, the relevant specifications and the recommended flow rates of reference books are often used in the design of river courses in Shanghai area, which is lack of strong pertinence. When I was working on the first phase of Changxing Island water system remediation project, we cooperated with Hohai University to conduct a physical model test and study on allowing non-flushing velocity to get more reliable results and effectively guide the engineering design work.
