摘　　要：针对青藏公路高原多年冻土地区的特殊需要 ,探讨了钢纤维水泥混凝土路面在保护冻土、控制融化沉降、保持路基稳定性方面的作用 .在室内实验、试验路的铺设与观测及热学计算的基础上 ,分析了钢纤维水泥混凝土路面在该地区的可行性和合理性 ,为我国寒区特别是多年冻土地区的公路建设提供了一个良好的路面结构形式 。This paper talks about the effects of steel fiber cement concrete pavement (SFCCP) on the protection of frost soil, and the control of the thaw settlement and the frost subgrade stable, in the special plateau permafrost region on which the Qinghai Tibet highway goes along. The feasibility and the rationality of the use of SFCCP in such region is analyzed on the base of the inner room experiments, outer door road paving, long term observation and the theory heat calculation, which concluded that we could use the SFCCP as highway pavement in the cold countries such as the frost region to protect the natural frost soil.
