０年代，甘肃省决定实施引洮灌溉工程，其中以在洮河九甸峡修建水库、防洪发电并自流引洮到干旱地区为最优方案。该工程地域辽阔，地层岩性及地质构造极为复杂，工程引水线路长，选择了以隧洞为主体、以明渠和渡槽相连接的线路方案。总干渠引水线路长１８５．６３ｋｍ、隧洞４１座、渡槽１９座、暗渠１６座、明渠总长１７．０１ｋｍ。引洮工程施工条件复杂，投资巨大，应精心设计，精心施工，以期尽快收到良好的社会效益和经济效益。
In the 1980s, Gansu Province decided to implement the irrigation project, in which the construction of reservoirs at Jiudian Gorge in Xiahe River, flood control and power generation and drainage from a river to an arid area was the optimal plan. The project has a vast territory, lithology and geological structure of the formation is extremely complex, the project diversion route is long, chose the tunnel as the main channel to connect the open channel and aqueduct program.
