摘要： 利用计算流体动力学方法并引入RNG (Renormalization Group) k-ε湍流模型，以山区复杂地形条件下的高层塔式仿古建筑为研究对象，分析了高层塔式仿古建筑表面的风压分布和风场绕流特性，以及建筑高度、建筑与山脚之间距离、山地地形等因素对风压和风场绕流的影响.结果表明：在不同的地形条件下，建筑表面的风压分布具有差异性；建筑表面风压绝对值随着建筑高度的增长而增大，随着建筑与山脚之间距离的缩短而减小；山地地形及其参数对建筑表面上部风压的影响明显大于对建筑表面下部风压的影响.
关键词: 塔式仿古建筑； 山区地形； 风荷载； 风场绕流
Abstract: Taking the antiqued high-rising towers under terrain as the research object, wind pressure distribution and wind field around the tower are analyzed by using the method of computational fluid dynamics and RNG (Renormalization Group) k-ε turbulence model. The influence on wind pressure and wind field related to building height, the distance from hillside to the towers and the kinds of terrain are analyzed as well. The results show that the wind pressure distribution varies under different undulating terrain. The absolute value of the wind pressure on the tower surface increases with the building height, however decreases against the distance from hillside to the towers. In addition, parameters such as undulating terrain configuration have greater influence on the surface wind pressure of upper tower than the bottom tower.
Key words: antiqued tower buildings; mountainous terrain; wind pressure; wind flow
