| 摘 要： | 假定管线穿越水平毗连的三种土介质，并与两交界面正交，求得管线与土的相互作用后，对管线进行了动力分析。结果表明，三种土介质场与两种土介质场地有根本不同，原因在于波在两交界面上多次反射与透射形成波的聚集。管线的动力反应取决于三种土介质的软硬程度，排列顺序及中间土介质的宽度。

| Abstract: | This paper describes the analysis of the dynamic responses of pipelines which are assumed to penetrate through three horizontally adjacent soil media and cross the two interfaces at a right angle and the results of the study on the pipeline soil interraction show that the dynamic responses of pipelines of the three soil site are materially different from those of the two soil site.The dynamic responses are determined by the stiffness ratios,sequence,and the width of the middle layer of the three soil media. |
