不同土壤结构对冻土深度影响探讨

Influence Discussion of Different Soil Structure on Frozen Soil Depth

根据我国北方某大型工程厂区内不同位置实测的12月至翌年3月的逐日冻土深度资料情况,证实了土壤结构对冻土深度有较大影响,并通过进一步分析,得到最大冻深在不同土壤结构中的影响系数。该影响系数可供工程设计人员参考使用,按不同土壤结构情况合理修正最大冻深值。

According to the real observed data of depth of frozen soil which was measured daily in a large project in northern China,from December to next March,it was confirmed that the soil structure had a great influence on the depth of frozen soil,and through further analysis,influence coefficients for the maximum frozen soil depth in different soil structure is obtained. The coefficients can be used for engineering design,and then the maximum frozen depth value can be adjusted reasonably according to the different soil structure.
