- 本文对埋地管道在断层运动作用下的特性参数进行了分析计算，按照我国现行规范给出的输油气埋地钢质管道抗震验算方法，对管线穿越角、管壁厚、埋深、土壤密度、管－土摩擦角等特性参数对管道抗震性能的影响进行了图形分析；对于给定的管线，通过改变其特性参数，利用计算机程序绘制的图形，可给出管线穿越断层区时满足抗震要求的各主要参数的限定值。此种分析计算对于管道的抗震设计与施工具有一定的实际意义。本文也把此种分析计算结果与Newmark－Hall、Kennedy的计算结果进行了比较。
This article analyzes and calculates the features and parameters of underground pipeline under ac-tion of the fault movement. It analyzes influence of feature parameters of pipeline crossing angle, wall thickness, barring depth, soil density and friction angle between pipe and soil upon pipeline's seismic resistance by means of graphics in accordance with the seismic resistant checking method of under-ground steel oilgas transmission pipeline of the executive specification. This analysis can give com-puter graphics and the limit of each main parameters satisfied with seismic resistance request through adjusting feature parameters of the known pipeline. This analysis and calculation have practical in-struction to seismic resistant design and construction. Finally it compares its analysis and calculation result with Newmark-Hall and Kennedy's calculation result.1998,2(2): 7-11,2 收稿日期：1997-7-15参考文献：
