为了扩大均摊恒定热流法的适用范围，对其进行修正，提出完全法和分段法。结合实际工程，分别采用2种方法对土壤温度场进行模拟分析。结果显示，利用分段法可以准确得出任意时刻土壤温度场；采用2种方法得到的周期时间点上的土壤温度场非常近似；在分析周期时间点上的土壤温度场，或进行长时间模拟计算，或对数据精确度要求不高时，完全法是方便和简捷的。指出2种方法各自的适用范围。

Revises the average constant heat flux method in order to extend its application scope,and presents the complete method and section method.Combined with practical engineering situations, simulates and compares the soil temperature fields obtained by the two methods.The results indicate that the section method is accurate and reliable to obtain the soil temperature field at any time.The soil temperature fields are almost the same at cycle time point using the two methods.When analysing soil temperature field at cycle time point or conducting a long-time simulation,or when the requirement for data accuracy is not high,the complete method is simple and convenient.Points out the application scope of the two methods.
