【摘要】：透水框架作为一种减速促淤的整治建筑物,近年来在航道整治工程逐步得到推广,在守护工程中应用最为广泛.长江航道规划设计研究院研发了一种新型透水框架——扭双工字型透水框架,并在南京以下12.5 m深水航道建设一期工程通州沙潜堤护底中进行了试验性应用.确定合理的透水框架护底检验标准,是保证防护效果的重要基础,而目前的航道整治工程质量检验标准,并未对此作出明确规定.通过水槽试验提出透水框架护底的检验标准,利用测扫声呐图像分析提出相应的检验方法,并进行了室内光学图像试验验证,符合较好.
[Abstract]:As a kind of regulation building which can slow down and promote siltation, the permeable frame has been gradually popularized in the waterway regulation project in recent years. The Yangtze River Waterway Planning and Design Research Institute has developed a new water permeable frame-twisting double I-shaped transmissible frame. The experimental application has been carried out in the bottom protection of Tongzhou sand submersible embankment in the first stage construction of 12. 5 m deep water waterway below Nanjing. It is an important foundation to ensure the protection effect by determining the reasonable inspection standard of the permeable frame protecting the bottom. However, the current quality inspection standard of waterway regulation project has not been clearly stipulated. Through the flume test, the inspection standard for the bottom protection of the permeable frame is put forward, and the corresponding inspection method is put forward by the analysis of sonar images. The experiment of indoor optical image is carried out and the results are in good agreement with each other.
