Study On Microstructure Change Of Soil In Slope Soil

This paper studies the soil reinforcement and microstructure analysis.The experimental study and theoretical analysis of variation of soil microstructure can provide the important basis for strengthening mechanism of macroscopic mechanics experiment of soil slope,and also have an obvious reality on engineering properties,the nature of the analysis and evaluation of soil engineering and its application.Study effects of external conditions on the strength of the stabilized soil,summarizes the main factors affecting the soil slope stability,to investigate the protective effect of curing agent on soil improvement and slope stability,through indoor soil test and SEM scanning electron microscopy test.Research on microstructure changes by SEM scanning electron microscope on the curing agent is added into the soil.Optimize the best dosage of curing agent and curing time,the micro structure parameters by using quantitative and fractal dimension to describe the variation of microstructure in the process of consolidation,the difference in micro structure changes to explain the macroscopic mechanical properties of the soil.Through the establishment of mechanical parameters and microstructure parameters,the relation between the fractal dimension to study the soil mechanics,behavior mechanism.The red soil mineral composition and the micro structure image features of plain soil and reinforced soil is came by the related experiment.The contact properties of the fine structure parameters corresponding to the corresponding mechanical analysis,changes with the structural parameters of the mechanical properties of the corresponding results.Summed up the essence of the curing agent after soil reinforcement the mechanism provides a theoretical explanation for the nature of the behavior mechanism of soil reinforcement.
