摘要
通过室内试验和试验路测试 ,建立了水泥—石灰综合稳定土和石灰稳定土 2种处治土路基回弹模量与饱和度之间的关系以及土张力与饱和度之间的关系 ;通过土张力的现场测试 ,并利用上述 2个关系可以预估路基回弹模量。研究表明 ,随土张力减小、饱和度增大 。
The relation between resilient modulus and saturation degree of two types of stabilized soils is formulated,and the relation between capillary and saturation of subgrade soil is also established in this paper.The resilient modulus of the stabilized soil pavement subgrades could be forcasted based on the relations mentioned above.It is shown that the resilient modulus of subgrade decrease significantly with the decreasing in capillary of soil and the increasing in saturation degree of soil.
