摘　　要：水利枢纽船闸改扩建是内河航道整治工程中的控制性工程,以右江金鸡滩水利枢纽二线船闸工程原型观测实践为例,对船闸改扩建原型观测的方法进行分析和总结,主要包括比降观测、表面流速流向测量、断面流量和流速流向观测、泥沙测验和底质取样等5个观测方法。通过现场实践生产,在枢纽上下游多维度同步观测和采样,并对观测成果进行统计、分析和研究,为枢纽船闸改扩建的规划、设计和施工等建设技术方案提供水文基础资料,为模型试验、航道整治工程提供准确的工程实施数据,值得类似项目借鉴和应用。The renovation and expansion of the ship lock of the water conservancy hub is a control project in the inland waterway regulation project.Taking the prototype observation practice of the second line ship lock project of the Youjiang Jinjitan hydro-junction as an example,this paper analyzes and summarizes the methods of prototype observation for ship lock renovation and expansion,mainly including five observation methods,such as gradient observation,surface velocity direction measurement,cross-sectional flow and flow velocity direction observation,sediment testing,and sediment sampling.Through on-site practical production,multi-dimensional synchronize observation and sampling are carried out in the upstream and downstream of the hub,and the observation results are statistically analyzed and studied to provide hydrological basic data for the planning,design,and construction technical schemes for the hub ship lock expansion and renovation,providing accurate engineering implementation data for model testing and waterway regulation project.It is worth learning and applying in similar projects.
