摘要
根据冻土蠕变试验数据的持点，指出采用幂函数关系回归冻土蠕变方程存在一些缺点，提出对试验后期数据的拟合应采用加权最小二乘法，这对确定冻土稳定蠕变的起始点和计算冻土结构变形量有一定的意义。
Based on the characteristics of data in frozen soil creep experiment,points out shortcomings in the regression of frozen soil creep law using power function. A weighed least square method is thus proposed under full consideration of the data in later stage of the experiment. It will help to determine the start point of stable creep stage of frozen soil and to calculate the deformation of frozen soil structure.
