Correlation Relationship Analysis of Physical Mechanics Properties and Pores Microstructures

Abstract

Fine-grained soil plays an important role in strength and deformation of dredger mud consolidation. The microstructure and mechanics would be related closely to each other by experiments, simulations and calculations. But with the exception of effective consolidation, the dredger mud with the fluency structure variation would be quantifiably explained about the variation by visible microstructures and the consolidation mechanics. Quantitative correlations between microstructures and macro properties had been evaluated. It had been demonstrated that mechanical properties of the SFG soil were closely correlated to the meso and the nano scale clusters of porosity and mineral.

Microscopic and mechanical properties of undisturbed and remoulded red clay from Guiyang, China

“…The microstructure of soil has obvious fractal characteristics 16,17 , with the mechanical properties of soil closely related to its microstructure 18 . The soil microstructure is reflected by some microstructure parameters, including the shape of the aggregate (size, shape and roundness of aggregate), the pattern of the aggregate (direction and arrangement of aggregate), pore characteristics (pore size and distribution), and connectivity (shape and distribution of cementation) 19 .…”
