摘要
地下管道工程的震害及功能失效对正常社会生产及生活有很大影响,地下管道工程抗震研究一直受到人们的高度重视。本文基于近10年来中国大陆发生的几次地震中收集到的地下管道工程震害资料,对各种管道震害现象进行了分析,总结了目前我国地下管道工程的震害特点,同时,对近年来我国几个典型城市地下管道工程震害预测结果进行了分析,得到了几点有益的启示。我国部分城镇地下管道的抗震能力不足,应采取有力措施予以增强。
The seismic damage and loss of service of buried pipelines may have great influence on the society,the seismic research on buried pipelines has always been highly valued. In this paper, the seismic damage characteristics of buried pipelines in several recent earthquakes of mainland of China are analyzed, such as Lijiang Earthquake in 1996, Kekexili Earthquake in 2001, Dayao Earthquake in 2003, and Dongwu Earthquake in 2004, etc. The results of earthquake damage prediction of buried pipelines in several typical cities are also investigated. The seismic capacity of buried pipelines in some towns and cities is not enough and the effective measures should be taken in order to improve this situation.
