摘要
针对工业取水对取水流量和取水保证率的特殊要求,结合兰州铝业有限公司自备电厂湟水河无坝取水工程,提出了一种新的适用于无坝岸边引水工程的河道整治措施——曲线型束水分沙导流墙,该导流墙基于弯道环流原理和汊道水流的相关理论,采用最小能耗率理论并结合具体河道的边界条件及水流泥沙特性而设计,有效地解决了由于天然河流年内洪枯变化较大及主流线位置变化所导致的取水保证率难以满足及推移质泥沙淤堵取水口等引水安全问题。
Aiming at the special requirements of industrial water diversion and diversion assurance rate,a new curved guide wall is proposed by combining the damless water intaking project of self-supply power plant for Lanzhou Aluminum Co.Ltd..It＇s designed with the principle of artificial bending circulation and fork channel flow theory.Based on the boundary condition and sediment characteristics of channel,the minimum energy consumption rate theory is adopted to effectively solve diversion safety problem caused by diversion assurance rate which aroused in large annual variation of flood-low water and main streamline position in natural river and sedimentation bed load blocked up with water intake.
