| description | In order to explore the influence mechanism of polyacrylamide on the compressibility of lime-stabilized soil,
polyacrylamide with different contents was added to lime-stabilized soil, and the relationship between the consolidation
coefficient and the consolidation pressure was obtained through one-dimensional laboratory consolidation experiment,
and samples were taken for nitrogen adsorption experiment and observation with solid microscope. The results show
that the microscopic image shows that the reaction of polyacrylamide with lime will form a spatial network structure;
0.24% polyacrylamide can effectively reduce the compression of lime stabilized soil, and the porosity ratio of solidified
soil can be increased by 15.4%, and the consolidation rate can be accelerated by 413.2%. The pore volume distribution
shows that the addition of polyacrylamide to lime stabilized soil can reduce the mesopore volume of the solidified soil
and produce ultra-large pores. At the same time, the porosity ratio of the solidified soil is increased, which is beneficial
to the drainage of super-pore water in the soil, accelerate the consolidation rate of solidified soil, shortens the time of
consolidation and stability of the soil. |
