【摘要】 天然河道上堰坝的砌筑阻断了鱼类的交流与繁衍,与传统工程鱼道相比,仿自然型鱼道由于构建了鱼类熟悉的水流流态,因而具有更高的过鱼效率。结合天台县始丰溪一处堰坝改造工程,根据地形特点、当地建筑材料等自然条件,从鱼道的设计理念、类型选择、构造布置、水力计算等方面入手,对仿自然型鱼道在堰坝工程中的应用进行了设计研究,可为生态鱼道的发展应用提供参考。更多还原

【Abstract】 The construction of the weir dam on the natural river course blocks the fish communication and reproduction. Compared with the traditional engineering fishway, the imitated natural-type fishway has the higher fish-passing efficiency due to the construction of water flow regime familiarly for the fish. Combined with a weir dam reconstruction project in Shifeng Creek of Tiantai County, according to the topographical features, local building materials and other natural conditions, from the design concept, type selection, structure layout, hydraulic calculation and other aspects of the fishway, this paper designs and studies the application of the imitated natural-type fishway in the weir dam engineering, which can be referred for the development and application of ecological fishways.更多还原
