高速公路路基内部含水率监测与分析

Monitoring and analysis of internal moisture content of highway subgrade

为了研究运营使用后路基含水率的变化情况,选取试验路段布置测点进行监测,分析一年中路基内部含水率的变化规律。通过分析监测结果,得出路基含水率与气温之间具有良好的线性关系,与降雨量之间不存在线性关系,与净降雨量之间线性关系不明显,但净降雨量较高的月份,路基内部含水量也较高,具有一定的规律性。

In order to study the changes in the water content of the roadbed after operation and use,the test road section was selected to arrange measurement points for monitoring,and the change law of the internal water content of the roadbed in a year was analyzed.By analyzing the monitoring results,it is concluded that there is a good linear relationship between the water content of the roadbed and the temperature,there is no linear relationship with the rainfall,and the linear relationship with the net rainfall is not obvious.The internal water content of the roadbed is also relatively high,with certain regularity.
