摘　　要：利用黄河粗泥沙集中来源区水文、地质研究成果以及实地调查和勘测资料,采用典型分析和综合对比分析的方法,依据现行规范和规定,以及提出的工程布局原则,通过对典型小流域建设目标分析、单坝工程设计、布局方案设置、控制面积对比、防洪能力对比、拦沙能力对比、淤地面积对比等,论证确定每条典型小流域中小型拦沙坝布局与规模成果。利用典型小流域布局成果,确定黄河粗泥沙集中来源区布置拦沙坝10 165座,其中中型拦沙坝1 995座、小型拦沙坝8 170座。The writer used the hydrology achievements of the concentrated source area of coarse sediment of the Yellow River, geological survey re- suits ,field investigation and survey data and adopted the methods of typical analysis and comprehensive comparison and analysis, based on the standards of the current norms and regulations and the engineering layout principle raised , through analyzing the construction goal of the typical small watemheds, the designation of each dam project, layout settings, the contrast of the eontrol area , flood control ability, the eontrast of the a- bility to block sand and the eontrast of silt ground area. The paper expounded the small and medium-sized cheek dam layout and scale of each typi- cal small watershed. The author used the results of the typical small watershed layout to study and determine the layout of debris-retaining structures of the concentrated source area of coarse sediment of the Yellow River.
