摘　　要：介绍了平推断层作用下管道最大轴向应变的计算方法可直接将管材的容许应变与管道的实际最大应变进行对比来判断管道的安全性物理意义十分明确该方法还可以同时给出管道的最大应力实际伸长量容许伸长量断层影响长度弹性变形区长度弹塑性变形区长度等相关参数以供理论分析或设计时参考s Introduced the calculating method of the maximum axial strain of the pipeline under the action of horizontal moving fault. Judgement of the safety of the pipeline can be carried out by comparison the allowable strain of pipe material with the actual maximum strain, the physical meaning is quite clear. With this method can be worked out the related parameters such as maximum stress of the pipeline, actual elongation, allowable elongation, fault effecting length, length of elastic deformation zone, length of elastic-plastic deformation zone, they are to be referred during theoretical analysis or designing.
