摘　　要：为解决松新鱼道在运行过程中鱼道进口处出现的不足,提高目标鱼类通过率,对现状鱼道进口段开展优化设计研究。通过在鱼道进口下游布置1段仿自然鱼道,仿自然鱼道布置于鱼道下游,上游至下游呈倒"八"字形,延长鱼类上溯通道、平缓流态的同时,通过收窄水面,维系通道内诱鱼流速,达到优化目标。根据对优化后的鱼道试验及监测结果,仿自然鱼道的修建提高了鱼道进口的吸引率,整体提升了松新鱼道的过鱼能力。To address the shortcomings at the entrance of the Songxin fishway during operation and improve the passage rate of target fish,an optimization design study is conducted on the current entrance section of the fishway.By arranging a natural fish passage downstream of the entrance of the fish passage,forming an inverted"eight"shape from upstream to downstream,the upstream channel for fish is extended and the flow is smooth.At the same time,the water surface is narrowed to maintain the flow velocity of fish in the channel,achieving the optimization goal.According to the optimized fishway test and monitoring results,the construction of a simulated natural fishway has improved the attractiveness of the fishway entrance and overall enhanced the fish passing capacity of the Songxin fishway.
