As the special soil
turfy soil and peat soil in China contained some similar properties with high void ratio
high water content
high organic content
etc. But turfy soil also had properties which difference from peat soil. In this paper
based on the formation of the cause and geological environment and geomorphologic characteristics of geological in the quaternary
took the typical and widespread turfy soil and peat soil regions for example
systematically discussed the material composition and macroscopic and microcosmic structural features
put further research on the physical chemistry mechanical characteristics. Then the come to the conclusion that the essential reason for difference between turfy soil and peat soil were decomposition degree and organic content. The result that worse engineering properties such as higher the moisture content
porosity
compressibility
internal cohesion and the lower specific weight
consolidation coefficient and permeability were due to the lower decomposition degree and higher organic content of turfy soil than peat soil. It can provide reference to the practical projects of turfy soil to distinguish peat soil according to this characteristic. (2012) Trans Tech Publications.
