摘要
由多年冻土引起的输油管道问题,主要有融沉、冻胀等不良地质现象。在多年冻土地区修建管道,该地区埋设管线因传热和震动引起冰层融化,产生冻胀、融沉问题,会使管线下沉或凸起,对管道建设产生不利影响。
The problems with oil transportation are caused by permafrost,including some bad geological phenomena,such as thawing settlement and frost heave.When a pipeline is laid in permafrost regions the pipeline laying can cause ice melting by heat transfer and vibration.This will induce such problems as thawing settlement and frost heave,both of which will bring adverse effects on pipeline construction.
