    砂土渗透变形类型统计分析研究

    STATISTICAL ANALYSIS AND STUDY ON SANDY SOIL PERMEABILITY DEFORMATION TYPE

    • 摘要: 土的渗透变形类型判别是渗透稳定性评价的基础。目前对碎砾石和黏性土的渗透变形类型看法是一致的,但对砂土的渗透变形类型看法尚不一致,且专门研究较少。为进一步研究砂土的渗透变形类型,收集了12个工程131个不同类型砂土试样,对其渗透变形试验结果进行统计分析,结果表明:各类砂土渗透变形类型均为流土。进一步理论分析也表明,砂土的渗透变形类型也应为流土。

       

      Abstract: The assessment of permeability stability is made based on the permeability deformation type of soil. At present, the views are same on the permeability deformation types of crushed gravel and cohesive soil, but different on the permeability deformation type of sandy soil, furthermore, the specific study is insufficient. In order to further study on the sandy soil permeability deformation type, statistical analysis is made on the permeability deformation base on 131 samples of different type sandy soil taken from 12 projects. The results indicate that the permeability deformation types for each sandy soil are both soil flow. And further theoretical analysis also shows the same conclusion.
