摘　　要：工程设计中,通常认为普通螺栓群弯矩受拉时,中和轴在弯矩指向一侧最外排螺栓处。这种假定有一定的不合理之处。本文作者通过建立计算模型,推导出中和轴位置的计算公式,继而应用实例进行验证,并提出了相应的构造措施限制。In engineering design, the natural axis is located assumably the extreme row which is directed by the moment. It is irrational partly about the assumption. In the paper, the author establish the counted model and deduce the formulas for the site of the natural axis and validate the formulas with engineering cases. At last, the author put forward the corresponding constructional details.
