摘　　要：以珠江三角洲水资源配置工程鲤鱼洲取水工程为例,建立水力物理模型对取水河段的水力特性、取水口的进水流态进行深入研究。试验显示,取水口设计方案存在因弯道水流、汊道水流及侧向引水等导致的进水流态不良问题,综合取水河段河势、取水口地形特征,提出基于优化进水角度及进水导墙体型、适应取水水域岸线形态的水流调控技术,可有效调整取水口水流分布,改善回流等不良流态,提高取水效率。This study utilizes the example of the Liyuzhou Water Intake Project of the Pearl River Delta Water Resources Allocation Project to establish a hydraulic physical model for an in-depth investigation of the hydraulic characteristics of the intake river segment and the inflow patterns at the water intake.Experimental results revealed that the design of the water intake faced challenges related to adverse inflow patterns caused by bend flow,branch channel flow,and lateral diversion.By integrating the river regime and topographical features of the water intake section,water flow regulation techniques were proposed based on optimized inflow angles and the geometry of guiding walls that adapt to the shoreline morphology of the water intake area.These techniques can effectively modify the distribution of inflow at the water intake,mitigate adverse flow patterns such as recirculation,and enhance water intake efficiency.
