This article analyzes the characteristics of permafrost earth, establishes mathematical model of earth thermal transfer, which consists of thermal transfer equation in thaw zone, the conservation relationship of heat quantity transferring from pipeline to earth and from earth surface to atmosphere, earth temperatures at thaw zone interface, heat transfer condition of solid phase changing into liquid phase at phase interface
文章分析了永凍土的特點,建立了永凍土地帶土壤傳熱數學模型:融化圈內外傳熱方程、管道向土壤和土壤表面向大氣所放熱量的守恆關系、融化圈界面處土壤溫度、相變界面處固相變為液相的傳熱條件。When a buried pipeline goes through permafrost zone, thermal action between medium in pipeline and permafrost occurs and causes the frozen earth thawing, so the thaw settlement forms around the pipeline
摘要埋地油氣管道通過永凍土地帶時,由於管內介質與周圍的凍土發生了熱力作用,使冰土解凍,在管道周圍形成融化圈。
