STATISTICAL ANALYSIS AND STUDY ON SANDY SOIL PERMEABILITY DEFORMATION TYPE

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.
