摘要
采用数值计算的方法对单排冻结管冻土壁温度场进行分析,研究界面的温度分布规律以建立冻土壁厚度、平均温度与岩土体的导热系数、岩土体的比热和含水量、岩土体的结冰温度和原始温度、盐水温度、冻结管外直径、间距及冻结时间等因素间的关系,为冻土壁设计和冻结施工提供参考。
In the paper, the finite-dement calculation was applied to analysis the temperature field of single freezing pipe. Through striding the law of temperature distributing to found the relation among the thickness of ice wall, average temperature, conductivity factor, specific heat, moisture content, freezing temperature and original temperature of rock and soil mass, temperature of salt water, external diameter of freezing pipe, spacing parameter and freezing period etc, which providing reference for designing of ice wall and constructing of freezing.
