摘　　要：通过结构受力模型分析了输电杆塔法兰在弯矩作用下的受力性能,推断出现行规范DL/T5154-2002《架空送电线路杆塔结构技术规定》中法兰受弯计算公式的缺陷。通过有限元计算结果与法兰真型试验结果证明了推断的合理性,在此基础上提出合理的法兰受弯模型与计算公式。The mechanical behavior of rigid flange joint under bending moment was analyzed.The imperfection of the calculation formula was given out.The difference among the calculation formula,finite element method and experiment test was compared;the results proved the rationality of the conclusion.On this basis,the reasonable computation model and the calculation formula of rigid flange joint were provided.
