| 摘 要： | 通过测试土样初始冻结温度,建立野外现场温度自动化远程实时监测系统,利用初始冻结温度等温线深度代替冻结锋面,计算季节冻土层厚度,为冻土学冻结深度观测自动化提供依据。试验结果表明:冻结过程相关系数为0.97,融化过程相关系数为0.98,整个冻融过程相关系数为0.98;用温度场冻结点等温线观测冻深的方案是可行的,可以实现冻融过程自动化实时监测,且观测精度较高。

| Abstract: | By testing the initial freezing temperature of soil samples,an automatic and remote real-time field temperature monitoring system was established.The thickness of seasonally frozen soil was calculated by substituting the freezing front by the depth of the initial freezing temperature isotherm so as to provide basis for the automatic observation of freezing depth in cryopedology.The test results show that the correlation coefficient of the freezing process is 0.97,that of the thawing process is 0.98,and that... |
