摘　　要：三角形螺栓球节点钢管塔是一种形式简洁、便于施工的钢塔。但由于其抗扭性较差，如果连接构造处理不好，很可能会造成事故，辽宁某通信公司一座５０ｍ高移动通信塔的倒坍就是一个实例。本文通过对倒塔时具体情况的调查研究及针对该塔体结构的具体计算，分析了造成事故的原因，最后提出了补救处理措施。Triangular steel pipe tower with bolted spherical joints is the kind of steel tower which is simple in style and convenient for construction . Yet due to its inefficiency in resisting torsion, it is liable to cause accident . A such tower with a height of fifty meters in Liaoning Province collapsed on Oct . 30th in 1996 is just a case of it . After researching thoroughly the collapsed tower with accurate computing of loads and theoretical analysis, the cause of the accident has been found out, and methods of remedy are proposed .
