| 摘 要： | 针对路基含水量年变化规律的地区差异性问题,在新疆地区典型路段埋设湿度传感器,对路基含水量进行观测,分析路基含水量随时间变化规律。通过路基含水量观测试验,研究了新疆不同地区路基含水量年变化范围及原因,采用双峰值函数对路基含水量随时间变化关系进行了拟合,得出了新疆各地区路基含水量年变化规律。结果表明:东疆、北疆、南疆地区路基含水量变化范围分别为2.47%~5.25%、1.38%~4.90%、2.06%~3.98%;由于新疆地区年降雨量小,蒸发量大,导致路基含水量最大的季节不在雨季,东疆与北疆地区路基含水量较大的季节在春融季节的3月~5月,以及雨季过后蒸发量相对较小的8月~11月,南疆地区路基含水量最大的季节只出现在春融季节的4月~6月。

| Abstract: | Aimed at regional differences of annual variation of water content in subgrade,the humidity sensors were installed to observe water content in subgrade at typical sections of Xinjiang,then the subgrade moisture variations with time was analyzed.The subgrade water content changes and causes in different regions of Xinjiang were studied,the relationship between subgrade water content changes with time were fitted by double peak function,so the annual variation of subgrade in different areas were obtained.The ... |
