摘　　要：引洮工程陇西县境内三干渠因年久失修,大咸河河岸受洪水冲刷比较严重,且河两岸无完整的防洪工程,汛期时有洪水泛滥,导致河道下切及冲刷较为严重。通过对三干渠相关河道进行河相关系分析和河道稳定河宽的计算,可知目前河道河相为河槽多成宽浅型式,河道纵横向不稳定,因此需要治理河道。The three main canals within Longxi County of the Tao River Diversion Project have been in disrepair for many years,and the banks of the Daxian River have been severely eroded by floods.There is no complete flood control project on both sides of the river,and there is flooding during the flood season,resulting in severe river channel cutting and erosion.Through the analysis of the river phase relationship and the calculation of the stable river width of the three main canals,it is known that the current river phase is characterized by a wide and shallow river channel,which is unstable in both longitudinal and transverse directions.Therefore,it is necessary to regulate the river channel.
