建设中的青藏铁路将穿越大片高温、富冰多年冻土地段,因此面临严峻的路基稳定问题。
The warm oil will produce thawing of ice rich soil adjacent to the pipeline when it crosses through permafrost zone, resulting in thaw settlement of the pipeline and variation of soil properties.埋地热油管道通过永冻地带时,会导致土壤解冻,进而导致管道沉陷和土壤物性参数变化。分析管道周围土壤融化圈变化对管道系统的设计、施工和管理是必需的。
