矩形双渡槽静风荷载的数值模拟研究

Study on numerical simulation of static wind load of the double rectangular aqueduct

采用数值模拟的方法对矩形双渡槽的风荷载进行了分析,计算了其在不同过水工况下槽体各部位的风压系数和整体风载体型系数。模拟结果表明,槽内是否过水对双渡槽的整体风载体型系数影响不大,但对其各侧壁的影响较大。

The method of numerical simulation was used to analyze the wind load of double rectangular aqueduct,the wind-pressure coefficient of each part of the aqueduct and the building type coefficient were calculated in different water transmission conditions.The simulation result showed that：whether the double rectangular aqueduct transmits water has little influence on the building type coefficient,but it has a great influence on the wind-pressure coefficient of the wall.
