摘　　要：针对地震烈度较高的地区间接空气冷却塔的设计中,存在塔的不同部位的计算控制工况不同,决定塔的断面尺寸选择不同的问题,结合工程实例,对高地震区塔的环基、塔筒、环梁在不同工况下的控制荷载组合,与低地震区间冷塔的设计进行对比分析,给出了当温度应力考虑徐变时、不考虑徐变时及对于8.75度的高烈度地震区域配筋量的选择。The calculation and control conditions are different for different parts of indirect dry cooling tower in high earthquake-intensity area, the section size of the tower is also different. Combined with an engineering for example ,the combination of control loads under different conditions about ring base ,shell and ring beam of tower in high earthquake-intensity area was compared with the tower in no earthquake area. At last reference and bases for design of indirect dry cooling tower in higher earthquake intensity were provided.
