| 摘 要： | 基于有限单元方法,建立了平面二维水流数学模型,针对取水口边界条件进行了研究.利用该模型计算了南海市第二水厂扩建工程前、后取水建筑物及其附近航道的流速、流向和水位等水流特性,着重分析了3种典型流量下取水口建筑物及其取水对航道通航条件的影响范围和程度,结果表明:取水工程不会对通航产生影响. |
| 关 键 词： | 有限元 数学模型 取水口 通航条件 |

| Abstract: | Based on the FEM method,a 2-D mathematical plane flow model is established to study the boundary condition of the water intake.The model was utilized to ananlyze the flow characteristics such as the flow velocity,flow direction and the water level,etc.,before and after the No.2 Nanhai water plant extension project was completed.This paper also focused on the analysis of the affected range and extent of the channel navigation condition by the water intake structures under 3 typical flow discharges.The results show that the water intake project will not cause adverse effect to the navigation condition. |
| Keywords: | FEM numerical model water intake project navigation condition |
