【摘要】 地下管线抗震安全性问题是生命线地震工程的重要研究内容, 大量震害表明地下管线, 特别是跨越断层的地下管线具有极大的脆弱性。分析跨断层地下管线的震害影响因素, 制定有效的工程措施对于提高实际地下管线的抗震性能具有重要意义。本文回顾了地下管线遭受震害的历史背景, 主要从断层参数、地震及场地参数以及管道参数三个角度分析了影响跨越断层地下管线震害的因素。在这些震害因素分析以及前人工作总结的基础上, 从宏观角度和具体措施两个方面, 提出了一些跨断层地下管道抗震的措施。更多还原

【Abstract】 The research of buried pipeline is important for lifeline engineering. However, many seismic damages show that buried pipelines are not so strong enough to resist the effect of the earthquake, so it is very important for us to analyze the influencing factors of the seismic damage on buried pipeline crossing a fault and to improve the behavior of the buried pipelines. In this paper, the seismic damages of buried pipelines in recent earthquakes are briefly reviewed, and the factors influencing the pipeline damages are analyzed from three aspects of fault parameters、 earthquake and site parameters as well as the pipeline parameters. At last, on the basis of these analyses and practical work, some measures on how to increase the capability of pipeline to resist earthquake are recommended from macroscopic point of view and practical use. In addition, the analyzing procedure for buried pipelines subjected to fault movement is emphasized in this paper.更多还原
