| 摘 要： | 通过对武（汉）广（州）客运专线武汉韶关段红黏土的工程特性研究，认为该地区红黏土液塑限高，饱和度和孔隙比大；具有较好的力学性能，压实性较低；先期固结压力远大于上覆土层自重压力，具有超固结性，具有固而不密特征；红黏土呈现出特殊的上硬下软的工程特性，超固结比和先期固结压力随深度增加而减小。这些研究成果为客运专线实体工程的修建提供了重要的指导和依据。

| Abstract: | This paper examines the engineering properties of red clay at the Wuhan-Guangzhou section of Wuhan-Guangzhou passenger dedicated railway line.The red clay in this area has high values in liquid and plastic limits,saturation,and porosity.It has good mechanical properties with low compactibility.The soil pre-consolidation pressure is far greater than its vertical overburden pressure.The soil is overconsolidated with high porosity.Besides,it was suggested that the red clay presents the peculiar engineering cha... |
