摘要
汉口Ⅰ级阶地广泛分布有粉质粘土、粉土及粉砂互层(3-5),厚度不均,分布不稳定,均一性差,各单层物理力学性质差异大,埋深大多位于地铁工程结构范围,对地铁工程有较大的影响。以王家墩CBD区3-5层为例,阐述3-5层的分布特征、物理力学性质及渗透性,重点探讨了该层的抗剪强度与渗透系数参数取值问题,分析其对地铁工程的影响。
The terraces Ⅰ in Hankou, embedded in the area of subway project, which has uneven thickness, instable distribution,inhomogeneity,is mostly composed by silty clay, the interbedded strata of silty clay and fine sand （3-5 layers）. Each single-layer has differences in physical and mechanical properties. The terraces Ⅰ has great influence on the subway project. Based on the example of the CBD in Wangjiadun, this paper has clarified the distribution characteristic of the 3- 5 layers, with its permeability, physical and mechanical properties, discussd on the shear strength of the layer parameters and values of permeability problems, analyzed its influence on the subway project.
