In order to study the inside changing regularity of cement-soil mesostructure and its effect on engineering characters

by the experiment of mesostructure change of different earth material cement-soil at different conservation temperatures and under uniaxial compression

to research the evolvement regularity of cement-soil mesostructure under load. Configuration parameters of mesostructure can be obtained by using the Geoimage software

and to make the quantitative analysis. The evolution charaters of proportion of pore surface area

grain discontinuity distributy

grain roundness

grain orientation

pores orientation and Euler number

and its action on compactness

cohesion

compression resistance of cement-soil can also be obtained. It’s certified that though soil sample isn’t failed

its mesostructure configuration and parameters are changed obviously; consequently engineering characters of cement-soil is effected apparenly.
