Abstract: 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.

Key words: cement-soil, mesostructure, quantitative analysis, configuration parameters
