摘要

介绍了地震灾害对长输油气管道三种危害方式,指出永久地面变形是造成管道失效的主要形式。列举了1971～2002年国内外地震灾害造成管道失效的典型案例,特别是阿拉斯加管道在穿越断层处采用立式支撑架的抗震设计取得了成功。分析了汶川大地震对兰成渝管道的危害形式及程度,认为滑坡和崩塌是此次地震对兰成渝造成威胁的主要灾害形式。
For earthquake hazards, three kinds of risk categories to long-distance oil and gas pipelines arepresented. It is pointed out that permanent deformation of earth surface is a major risk led up to pipeline failure. Typical cases from 1971 to 2002 in pipeline failure reduced by earthquake at home and abroad are provided.especially the case of successful antiseismic deign in Trans-Alaska Oil Pipeline, in which vertical supports are used in fault crossing. Hazard category and hazard level of "5. 12 Wenchuan Earthquake" forLanzhou-Chengdu-Chongqing Products Pipeline is analyzed in detail. It is considered that landslide and avalanche from the earthquake are main hazard categories to the pipeline.
