摘要
论述了在冻土地带管道工程建设的特殊性,通过对冻土地带冻融过程、规律及对埋地管道影响的分析,指出了冻土地带管道建设遇到的两个主要问题是冻胀破坏和融沉破坏。简要介绍了冻土的分类、特性及国内外冻土地带管道建设的研究情况和防治冻害的措施,归纳总结了冻土地带管道敷设的几种方式以及寒冷地区管道保温材料和技术,对冻土地带管道建设的关键问题进行了讨论,并提出了建议。
This pa per describes particularity of pipeline construction in frozen earth region,int ro-duces classification and characteristics of frozen earth,research work of p ipeline construction in frozen earth region and measures against frozen harm.It summarizes several ways of pipeline laying in that re-gion and some insulatio n materials as well as related techniques.The key problems about pipeline con-struction in that region are discussed and the beneficial suggestions are put forward.
