| 摘 要： | 热棒主要是在冬季将地下的热通过热棒导向大气,使冻土范围和冻土上限都变大,这样使冻土路基更加稳定.由于热棒只能影响一定的区域,所以热棒的埋设位置对热棒保护路基土有很大的影响,本文通过MRDT600温度监测系统对埋设直插型热棒的试验路路基与埋设了斜插型热棒的试验路路基进行温度监测.通过对监测的温度数据进行分析和对比,总结直棒、斜棒与L型热棒在保护冻土路基方面的优缺点.

| Abstract: | The hot rod is placed underground to transfer the hot to the atmosphere in the winter, which can enlarge the scope of permafrost and the upper limit of permafrost and make the permafrost roadbed stabilized. Because hot rod can only affect certain areas, the embedding location of hot rod has great impact on the protection effect of embankment soil. In this paper, the temperature of tested road subgrades which were embedded with straight DIP type hot rod, oblique inserting type hot rod, and L-type hot rod were monitored using MRDT600 type temperature monitoring system. Through the data analysis and comparison, the advantages and disadvantages of the three types of hot rods were summarized. |
