中文摘要：
修筑路基后土体水分变化是影响路基稳定性的重要因素,然而关于路基土体水分变化认识是极为缺乏的.采用了pF-meter传感器来监测土体温度和水分变化,获得了近3a的连续监测数据.结果表明,pF-meter较好地反映了路基土体温度和水分变化特征以及土体水分迁移特征.但是,pF-me-ter传感器不能定量地给出土体水分变化,这限制了pF-meter在土体变化监测中的应用.
英文摘要：
Soil moisture change is one of the important factors of affecting roadbed stability after embankment constructed.However,there is lack of understanding of moisture change of roadbed soil.In this article,pF-meter sensor is used to measure the change of soil temperature and moisture and then continuous measurement data were obtained for three years.The monitoring results show that pF-meter can indicate better the features of soil temperature and moisture and soil moisture transfer within an embankment.Unfortunately,pF-meter cannot show the quantitative change of soil moisture,and then application of pF-meter to monitor the change of soil moisture during the process of soil freezing and thawing is confined.
