摘　　要：在浙江省美丽河湖建设行动的推动下,对沿河溢流堰坝的新建和改造十分必要。筑坝材料的选择上,表明粗糙度是影响泄流能力的主要因素之一。为探究溢流堰坝的表面粗糙度对泄流能力的影响,通过数值模拟的方法,研究折线型溢流堰的表面粗糙度大小及其分布和流量系数的关系。结果表明,相对于折线堰的上下游坡面,堰顶的粗糙度是影响整体泄流能力主要因素,在小流量条件下的尤为显著。研究结果对深化溢流堰的认识,促进筑坝材料的研究创新和溢流堰改造工程的进步具有重要的学术意义和实用价值。Under the promotion of the beautiful river and lake construction in Zhejiang Province,it is necessary to build and transform the overflow dam along the river.The selection of dam materials shows that roughness is one of the main factors affecting the discharge capacity.In order to explore the influence of surface roughness of overflow weir on discharge capacity,this paper studies the relationship between surface roughness and its distribution and discharge coefficient by numerical simulation.The results show that the roughness of weir top is the main factor affecting the overall discharge capacity compared with the upper and lower slopes of the broken line weir,especially under the condition of small discharge.The research results have important academic significance and practical value to deepen the understanding of overflow weir,promote the research and innovation of dam construction materials and the progress of overflow weir renovation project.
