摘要
对埋地管线在均匀和非均匀土介质中的地震反应进行分析研究．结果表明，在地震行波作用下，不均匀土介质中埋地管线的轴向应变同均匀介质中管线的轴向应变相比，增大系数为１．５０左右．
This paper analyses the seismic response in uniform and nonuniform soil mediumfor buried pipelines. The results show that under the action of seismic harmonic waves the increment coefficient of axial strain for buried pipelines in nonuniform soil medium is about 1. 50 ascompared with that in uniform soil medium.
