近二十年来,由于控制大气污染的要求日益迫切,伴随着电子计算机在结构设计上的应用以及滑模施工技术的广泛推广,因而钢筋混凝土高烟囱的建造有了很大的发展。目前,世界各国的高烟囱巳经突破了300米高度,其最高者巳达到381米,例如: In the recent two decades, due to the increasingly urgent need to control air pollution, the construction of reinforced concrete high-rise chimneys has been greatly developed along with the structural design of electronic computers and the extensive promotion of sliding-mode construction technology. At present, the high chimneys in various countries of the world have already exceeded the height of 300 meters and the highest one has reached 381 meters. For example,
