摘　　要：水电站截流设计、组织及施工的合理性直接决定着截流成败和整个工程的施工进度。本文以汉江新集水电站现场施工为例,分析了坝址区的地质条件、水文气象,并结合现场地形地貌,确定截流标准、戗堤断面、截流方式、截流物料种类及数量,详细阐述了截流施工规划设计、截流施工情况,可为类似平原型河谷地貌的截流工程提供参考。The rationality of diversion design,organization,and construction for hydropower stations directly determines the success or failure of diversion and the overall progress of the construction project.Taking the on-site construction of Xinji Hydropower Station on the Hanjiang River as an example,this paper analyzes the geological conditions and hydro-meteorological factors of the dam site area.Combining the on-site topography and geomorphology,it establishes diversion standards,weir cross-sections,diversion methods,types and quantities of diversion materials.The paper provides a detailed exposition of diversion construction planning and design,as well as the diversion construction process,offering valuable insights for diversion projects with similar plain-type river valley landforms.
