摘要
本文讨论了在北极永冻土和非连续永冻土地带设计,建设,操作大直径,高压力天然气管道的特殊技术。特别提到在冰冻温度以下管线的操作,利用冰路,冬季建设,以及减缓冻胀和融沉的方法。首先,将介绍永冻土地区的特点,以及环境与天然气管线建设的内在联系,并说明如何在设计中克服永冻土所带来的困难。第二,将要考虑北极输气管线建设中的必要的改进技术,包括利用冰路,因为管线从北极向南延伸,会通过非连续冻土地带,在这里出现了一系列问题,本文讨论了这些问题及它们的解决方案。
In this paper i shall discuss some special techniques which arctic gas designed to construct and operate a large diameter,high pressure natural gas pipeline in permafrost and discontinuous permafrost.I will first cover permafrost and its interractions with a pipeline and then discribe how the pipeline disigned to overcome the problems caused permafrost.Secondly,we will consider the necesssarily innovative techniques that would be used to construct the line,including the use of ice roads.As the line proceeds...
