【摘要】 新光大桥是广州市拟建新光快速路的控制性工程,该桥梁两座主桥墩位于广州片网河主要的行洪纳湖通道之一——后航道上。为评价该工程兴建后对后航道及其相邻河道行洪纳湖可能带来的影响,分别对大范围一维网河数学模型和工程局部河段平面二维数学模型进行了行洪纳潮数值计算,并对该工程在河床和堤防稳定、防洪避险和抢险通道、通航和潮排潮灌等方面的影响进行了分析,提出了消除和减少对河道行洪纳潮不利影响的措施,从而为该工程的建设和审批提供了必要的科学依据。更多还原

【Abstract】 Xinguang Bridge is the control engineering of Guangzhou Xinguang Express Way. Two main piers of the bridge located in Houhangdao river, which is the main flood and tide way of Guangzhou net river. To evaluate the flood and tide influence of the bridge, mathematical models of large range one-dimensional net river and local two-dimensional were established for numerical calculation. The influence such as stabilization of river basin and flood flanking, way of flood prevent and control, navigation and tide irrigation flood were also analyzed. The measures for reducing disadvantage influence were put forward to provide science basis for this engineering.更多还原
