采用多区域网络模型 CONTAM 3．1模拟某虚拟千米建筑的冬季热压变化规律，选取大连地区为代表城市，详细分析了千米建筑中不同孔口两侧的压差和空气流量，并与其他5个城市的模拟结果进行了对比分析。提出采取多种有效措施来减小超高层建筑的热压作用。模拟分析表明，冬季超高层建筑中很多楼层的孔口两侧压差远远超过规范要求。若千米建筑建于我国北方，必须采取多种设置阻隔的方法，削弱热压对系统运行和人员疏散的不利影响。

Uses CONTAM 3.1 software based on the multi-zone network model to research the features of thermal pressure in a virtual 1 000 m skyscraper in winter.Studies the pressure distribution and air flow rate of different orifices in the 1 000 m building in Dalian,and compares the simulation results with those of the five representative cities including Dubai,Guangzhou,Shanghai,Beijing and Harbin.Proposes different measures to decrease the thermal pressure of super high-rise bwildings.Simulation analysis results show that the orifice pressure values in many floors exceed regulatory requirements.Diverse settings of separation in both vertical and horizontal partitions should be considered to weaken the adverse impacts on system operation and evacuation.
