摘要
基于一些路基检测资料,对粒径改良路基、通风管路基、综合路基等五种路基的试验效果进行了对比分析,分析表明:粒径改良路基具有良好的冷量交换与热屏蔽双重作用,最后利用导热学与多孔介质理论,简单介绍了粒径改良路基温度场计算方法,并在此基础上给出了多年冻土地基融沉量的计算方法。
On the foundation of inspection materials of roadbed, the paper compares and analyzes test effects of five kinds of roadbed, for example, size improved roadbed, ventilating pipe roadbed, general roadbed and so on. The results show that size improved roadbed maintains good eapabihty of cold exchange and heat shield. At last, making use of thermal study, it introduces briefly about the calculating methods of size improved roadbed temperature field, and at base of this, it provides the calculating methods for heavy financial of many years frozen earth roadbed
