摘要
电力线路电塔是河道中的常见工程,其对河道洪水流场影响尚缺少详细的分析成果。文章针对辽河中辽中电力线路电塔,采用HEC-RAS软件和标准湍流模型对辽河河道和电塔桩基附近水流流场进行计算分析,通过区分主槽和滩地两种情况,在影响范围、回流、涡街等方面得出结论。
Electric power line tower is a common project in river channel,detailed analysis is still lacking on how it affects the flow field of a river. This paper uses the HEC-RAS software and the standard turbulence model to calculate and analyze the flow field near the Liaohe River and tower pile foundation based on the electric power line tower in Middle Liaoning Province,and comes to the conclusion on affected area,reflux and vortex etc by distinguish the main channel and floodplain.
