从路基土的物理力学性质出发,利用灰色系统的理论方法——灰色关联分析法,对软土路基承载力进行研究,得到各指标对路基承载力的影响程度,并指出压缩模量对软土地基承载力影响最大,且路基承载力随压缩模量的减小而减小。%From the physical features of the roadbed soil,the paper adopts the gray relation theoretical methods,the gray-relation analysis method,to research the loading capacity of the soft-soil foundation,concludes the influential degrees of the indexes on the loading capacity of the foundation pit,and points out the compressive modulus has the greatest influence on the loading capacity of the soft-soil foundation,and the loading capacity of the roadbed reduces along with the decreasing compressive modulus.
