基于数值风洞的机场塔台幕墙安装风况分析

Wind Condition Analysis for Airport Tower Curtain Wall Installation Based on Numerical Wind Tunnel

使用CFD软件对某机场塔台幕墙在水平和高度方向上不同安装顺序与安装阶段的风场进行了模拟,对各测点的风场数据进行了分析。研究表明,塔台幕墙施工过程中的风场变化主要受到水平方向施工顺序的影响。在水平方向上,优先封闭主要迎风面幕墙能有效减小后续幕墙施工时的场风压;而在高度方向上,从上至下的安装顺序对后续幕墙风场干扰相对较小一些。

Utilizing CFD software,the wind fields surrounding an airport tower's curtain wall are simulated across various installation sequences and stages in both horizontal and vertical dimensions,and the analyses of wind field data at multiple measurement points are conducted.Results reveal that changes in the wind field during tower curtain wall construction are predominantly influenced by the sequence of construction in the horizontal dimension.Closing the main windward-facing curtain wall as a priority significantly reduces the wind pressure during subsequent installations.Additionally,the installation sequence from top to bottom vertically causes minimal disturbance to the wind field in subsequent installations.
