| 中文摘要: |
| 基于国家水专项太湖贡湖湾示范区水质水量调控的需求，构建了示范区的等比例缩放实体模型。通过研究模型中4种不同调水方案的效果，为示范区调水技术的比较与选择提供决策依据。研究中，通过测定模型中5个断面的流场数据，判断引水方式对模型流场的影响，以此评价不同调水方案效果。同时以墨汁作为示踪剂，通过不同引水放流方式下示踪剂的扩散场变化，验证不同断面流速测定对整个区域流场判断的准确性，从而分析引水放流方式对水质的影响。 |
| 英文摘要: |
| A proportional physical model,in accordance with the demonstration area which locates in Gonghu Bay,Taihu Lake,was constructed to meet the demand of controlling both quality and quantity of water within that area for the state water special project.The effects of four diversion methods in the models would be studied in order to provide arguments for making decisions between diversion methods for the demonstration area.When conducting the study,the influences to the model′s flow field,assessed by measuring flow field data at five different cross sections,would be deemed as indicators for evaluating different diversion methods.Meanwhile,ink was chosen as a tracer and the spreading field changes of the tracer caused by different diversion methods would verify conclusions to the flow field.Therefore,an analysis could be conducted for the impact to water quality caused by the methods.The study provided a helpful reference for deciding the diversion method for the demonstration area. |
