埋在地下的生命线，例如石油、天然气、水和下水道管道在最近的地震中受到严重破坏，例如1971年美国圣费尔南多地震，1976年中国唐山大地震和1978年日本宫城县大地震等。美国和其他许多国家已经开始研究这些埋在地下的生命线的抗震性能。已经提出了各种分析模型。然而，只有有限的实验研究。埋地生命线的地震破坏源包括滑坡、构造升降、土壤液化、断层位移和地面震动（波传播效应）。本文研究了埋地生命线系统在地表断层和地震作用下的行为。对影响地震反应的土壤参数的作用和发展进行了讨论。本文的范围是分析研究各种土壤和土壤结构相互作用参数的影响，埋地管道的地震反应，报告目前可用的物理数据，这些和相关参数的立即应用，并描述实验，以获得更多的信息土壤抗纵向管道运动的特性。
Buried lifelines, e.g. oil, gas, water and sewer pipelines have been damaged heavily in recent earthquakes such as 1971 San Fernando Earthquake, in U.S.A., 1976 Tangshan Earthquake, in China, and 1978 MiyagiKen-Oki Earthquake, in Japan, among others. Researchers on the seismic performance of these buried lifelines have been initiated in the United States and many other countries. Various analytical models have been proposed. However, only limited experimental investigations are available. The sources of earthquake damage to buried lifelines include landslide, tectonic uplift-subsidence, soil liquefaction, fault displacement and ground shaking (effects of wave propagation). This paper is concerned with the behavior of buried lifeline systems subjected to surface faulting and ground shaking. The role and development of soil parameters that significantly influence the seismic responses are discussed. The scope of this paper is to examine analytically the influence of various soil and soilstructure interaction parameters to the seismic responses of buried pipelines, to report the currently available physical data of these and related parameters for immediate applications, and to describe the experiments to obtain additional information on soil resistant characteristics to longitudinal pipe motions.
