| 摘 要： | 基于青藏公路黑马河试验段碎石垫层路基近1 a的温度、水分监测资料,初步分析了碎石垫层路基温度,水分的发展与分布特征以及造成这些差异的原因,并与传统的砂砾垫层比较.结果表明：碎石垫层加隔水土工布能够更好的削弱毛细水自下而上的迁移,起到了一定的隔水排水效果,对于防治季节性冻土路基冻胀病害具有积极作用.

| Abstract: | Based on the monitoring data of moisture and temperature along the National Road 109 in Qinghai Province,the changes and induced causes of temperatures and moistures at different positions of an embankment under the action of external climate conditions were systematically analyzed.The change rates and induced causes of moistures for the traditional gravel embankment and the crushed rock mat embankment with waterproof geotextile were discussed.Further more,the effects of these differences on the frost heavi... |
