摘要
Abstract
The vertical-slot fishway and the natural imitated fishway were studied through hydraulics experiment by using the normal integral model with the scale of l:20.The variation of hydraulic factors such as water level, gradient ratio and flow rate in the fishway with different flow conditions were mainly studied.Then the primary and secondary structure,length,bottom slope,slit width and pool room -number of the fishway were optimized.The fishway optimization scheme for Yilan navigation-power junction project was proposed through comprehensive comparison of fishway general layout,pool room structure,discharge volume,water level,gradient ratio changes,flow velocity variation,fishway construction,operation and maintenance.关键词
