黄土路基湿度变化规律跟踪观测研究

The Study on the Tracking and Observation of Loess Subgrade Humidity Variation Law

为提升公路的耐久性,需准确地掌握黄土路基的湿度变化规律。通过在黄土路基外侧行车道下方布设温湿度传感器,跟踪观测施工完成后路基的湿度变化规律,分析路基湿度变化的影响因素及变化规律。研究认为:进入秋冬季节,路基表层的湿度增加,内部湿度降低;在春暖季节,路基表层的湿度降低,内部湿度增加;降雨会增加路基湿度提升的速率,应采取足够的措施降低路基湿度增加幅度及速率。

Through setting the temperature and humidity sensors below the outer driveway of the loess subgrade, this paper had the tracking and observation of subgrade humidity variation law after the completion of the construction, analyzed the influencing factors and variation laws of subgrade humidity changes.
